MATH233 Unit 4 Individual ProjectNAME (Required): _____________________________Dr. Claude Shannon (1916 – 2001), “the father of information theory,” observed that the maximum error-free capacity in bits per second (bps) obtainable in a communication channel can be found by the Shannon-Hartley equation:bits per secondAbove, , is the bandwidth of the channel in Hertz and is the signal-to-noise ratio of the channel. Since 0 does not make sense in this situation, assume that the formula below is correct:This is a “pure” number with no unit labels on it. The value of is called Shannon’s Capacity Limit or channel capacity. This is the theoretical upper limit for the bits per second through the channel with a specific value and a specific given channel frequency bandwidth, , in Hz.

Different jobs pay different amounts, but all employees have
one thing in common. They pay taxes.
During this unit, you will explore pay amounts and federal
income tax.
First you’ll find the mean pay rate for a job you’re
interested in. Then you’ll use that figure to complete a pay stub, a W-2, and a
1040. Finally, you’ll compare differences in employment levels and pay rates
for your chosen job throughout the United States.
Schedule of Completion
Suggested Time to Complete and What to Turn In
Project Research: 1 day. No submittals.
Project Writing: 3 days. Submit Lesson Checkpoint: Paycheck
Deductions.

Project Research
1. Go to the website for the U.S. Bureau of Labor Statistics:
www.bls.gov. Under the Subject Areas tab, look under Pay & Benefits, and
choose Wages by Area & Occupation. Then select the link for the National
Wage Data for over 800 occupations.
2. You will first see a list of major occupational groups. Below
this list is the full table of jobs. From this list, select a job that you are
interested in. Do not pick the occupation
used in the project sample. Notice that you can select a link from the
major occupational group’s list to automatically move to a certain part of the
table.
(a) In the list, you will see rows for general categories, such as
Secretaries and Administrative Assistants. These categories do not have active
links (not underlined). They are followed by detailed occupations under that
category, such as Legal Secretaries and Medical Secretaries. These have active
links (underlined). Choose a more
detailed (underlined) occupation.
Tip: If you cannot find a particular
occupation you are looking for, try different wording. For example, look for musician instead of rock star.
(b) Select the link for your chosen occupation. You will see a brief
description of the job followed by mean wages.
3. Open your presentation. On slide 1, type your name. On slide 2,
record the occupation title, occupation code (shown in the form xx-xxxx), mean
hourly wage, and annual mean wage of your chosen career. If one of these
amounts is missing, calculate it. Assume working 40 h/week for 52 weeks. Then
summarize the duties of an employee with this job. Do not copy the description
from the website word for word.
Project Writing
1. Complete Lesson Checkpoint: Paycheck Deductions, an online,
ungraded assessment. You’ll practice calculating Social Security and Medicare
taxes—a skill essential to completing your project. Reach out to your teacher
with any questions you have after taking this assessment.
2. Open your presentation. On slide 3, complete the pay stub.
(a) Choose a pay period. Choose weekly, biweekly, semimonthly, or
monthly. Then choose if the job is paid by hourly wages or by a given salary.
Complete the first sentence on the slide.
(b) Use the mean wages on slide 1 to calculate the gross pay for
your chosen pay period. On the slide, briefly show or explain how you
determined this amount. For example, multiply the hourly wage by 40, or divide
the annual wage by the appropriate number of pay periods. (Note: Assume 40 hours if working an hourly wage.) Fill in the gross
pay amount on the pay stub under Gross Pay.
(c) Use the gross pay amounts and the table below to determine the
amount of federal income tax withheld. (Note:
This table estimates a typical
withholding amount for a single employee with no dependents. Actual federal
withholding amounts in the real world will differ.)
Annual Gross Income
Federal Income Tax
Withheld
Over $10,000 and up to $20,000
6% of gross pay
Over $20,000 and up to $40,000
10% of gross pay
Over $40,000 and up to $60,000
12% of gross pay
Over $60,000 and up to $80,000
16% of gross pay
Over $80,000 and up to $100,000
18% of gross pay
Over $100,000 and up to $120,000
20% of gross pay
Over $120,000 and up to $140,000
21% of gross pay
Over $140,000 and up to $160,000
22% of gross pay
Over $160,000 and up to $200,000
23% of gross pay
Over $200,000
25% of gross pay
Fill in the amount
withheld for federal tax on the pay stub next to Federal Tax.
(d) Use the gross pay amount to calculate the Social Security and
Medicare taxes. Fill in these amounts on the pay stub.
(e) Use the gross pay amount to determine the state tax. Some states
have no income tax. The tax rates for states that do have an income tax vary.
For this project, assume a 3% state income tax.
(f) Find the total of the taxes. Fill in the total tax amount on the
pay stub under Tax Deductions.
(g) Use the list below to choose voluntary deductions. (Note: This table gives sample amounts
only. Actual deductions in the real world will differ.) Choose at least two of
these deductions.
·
Retirement: Calculate 5% of
gross pay.
·
Health Insurance: Use an
annual deduction of $1650 to calculate the deduction for the pay period.
·
Life Insurance: Use an
annual deduction of $400 to calculate the deduction for the pay period.
·
Disability Insurance: Use
an annual deduction of $150 to calculate the deduction for the pay period.
Fill in the
calculated amounts on the pay stub. Fill in $0 for deductions not chosen.
(h) Find the total of the voluntary deductions. Fill in the total
amount of voluntary deductions on the pay stub under Voluntary Deductions.
(i) Determine the net pay by subtracting the tax deductions and the
voluntary deductions from the gross pay. Fill in the net pay on the pay stub
under Net Pay.
3. Open your presentation. On slide 4, complete the W-2.
(a) Box 1: Enter the annual mean wage by multiplying the gross pay
on your pay stub by the appropriate number of pay periods.
(b) Box 2: Enter the total amount of federal income tax withheld for
a full year by multiplying the amount of federal tax withheld on your pay stub
by the appropriate number of pay periods.
(c) Box 3: Social Security taxes are taken only up to a certain
amount of pay, and this amount changes every year. For the purpose of this
project, use $120,000 as the limit.
·
If the amount in Box 1 is
less than or equal to $120,000, then enter the amount in Box 1 into Box 3.
·
If the amount in Box 1 is
greater than $120,000, then enter $120,000 into Box 3.
(d) Box 4: Enter the total amount of Social Security tax withheld,
which is 6.2% of the amount in Box 3.
(e) Box 5: Enter the annual mean wage, from slide 1. (Notes: Unlike Social Security, there is
no limit on how much Medicare tax is taken out. Also, in the real world, this
amount can be larger than the amount in Box 1 if your employer contributed
money to your retirement plan.)
(f) Box 6: Enter the total amount of Medicare tax withheld, which is
1.45% of the amount in Box 5.
(g) Box 13: If you chose retirement as a voluntary deduction on your
pay stub, then type an X in the appropriate spot.
(h) Box 16: Enter the amount in Box 1.
(i) Box 17: We are assuming a 3% state income tax, so enter 3% of
the amount in Box 16 into Box 17.
Note: For the purpose of this project,
ignore the shaded boxes. In the real world, you may see some of these boxes
filled in.
4.
Open your 1040
spreadsheet, which you saved with your name. In the 1040 tab, part of a blank
1040 is shown on the left. Instructions for filling out the 1040 are shown on
the right. Follow all those instructions, in order. Tax Tables and Tax Formulas
are given in the other two tabs of the spreadsheet. Round all values to the
nearest whole dollar. You do not need to show dollar signs on this form. Save your work when you are finished. You
will submit this document along with your presentation.
5. Open your presentation. On slide 5, type in the following
information from your 1040, and then write the final statement about whether an
employee with this 1040 would receive a refund or owe money, and give the
amount that the person would receive or pay.
·
Total income (from Line 22)
·
Adjusted gross income (from
Line 37)
·
Taxable income (from Line
43)
·
Tax (from Line 44)
·
Total payments (from Line
72)
·
The amount overpaid (from
Line 73) or underpaid (from Line 76)
Project Reflection
1. Go back to the website for the U.S. Bureau of Labor Statistics
and select the link for the occupation you chose. Scrolling down, you will find
maps and tables with employment levels and mean pay rates for states and
localities. Look through this information.
·
Each map has a key that
shows what the different colors on that map represent.
·
The location quotient
indicates the job concentration within a given area. The greater the location
quotient, the greater the concentration of jobs in that area.
2. Open your presentation. On slide 6, write a discussion that
addresses each of the following for your chosen job:
·
Which areas of the United
States have the highest levels of employment? Which areas have the lowest
levels of employment? Why do you think this might be?
·
Which areas of the United
States have the greatest mean pay? Which areas have least mean pay? Do you find
any of this surprising? Why or why not?
·
Use your research to
answer: If someone who wanted this job could move anywhere in the United
States, where would you suggest the person move to and why?
Submission
Confirm that your project contains all your work:
·
General job information
·
A completed pay stub
·
A completed W-2
·
A completed 1040
·
Your reflection on regional
differences
Submit your project (both
your presentation and your 1040) to your teacher

WEEK 6 Assignment: Testing Hypotheses for Means
Assignment: Testing Hypotheses for MeansThis week you have explored three different approaches to t tests. By this point, you know that each test has assumptions about the data and type of research questions it can answer. For this Assignment, you will be provided with three scenarios. As you read the scenarios, be sure and think about aligning the appropriate t test with the question. Consider whether the data are independent samples and if two samples are being compared.To prepare for this Assignment:Review the Learning Resources and the media programs related to t tests.For additional support, review the Skill Builder: Research Design and Statistical Design and the Skill Builder: Hypothesis Testing for Independent Samples t-test, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.Also, review the t test scenarios found in this week’s Learning Resources and consider the three different approaches of t tests:Independent sample t testPaired sample t testOne sample t testBased on each of the three research scenarios provided, open the High School Longitudinal Study dataset or the Afrobarometer dataset from this week’s Learning Resources using SPSS software, then choose and run the appropriate t test.Once you perform your t test analyses, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 2 to 3-paragraph analysis of your t test results for each research scenario and include the SPSS syntax and output. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1SES. Do not forget to evaluate if the t test assumptions are met, justify the selection of type of t test, and report the effect size. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research questions, and output.

Project Research
1. Go to the website for the U.S. Bureau of Labor Statistics:
www.bls.gov. Under the Subject Areas tab, look under Pay & Benefits, and
choose Wages by Area & Occupation. Then select the link for the National
Wage Data for over 800 occupations.
2. You will first see a list of major occupational groups. Below
this list is the full table of jobs. From this list, select a job that you are
interested in. Do not pick the occupation
used in the project sample. Notice that you can select a link from the
major occupational group’s list to automatically move to a certain part of the
table.
(a) In the list, you will see rows for general categories, such as
Secretaries and Administrative Assistants. These categories do not have active
links (not underlined). They are followed by detailed occupations under that
category, such as Legal Secretaries and Medical Secretaries. These have active
links (underlined). Choose a more
detailed (underlined) occupation.
Tip: If you cannot find a particular
occupation you are looking for, try different wording. For example, look for musician instead of rock star.
(b) Select the link for your chosen occupation. You will see a brief
description of the job followed by mean wages.
3. Open your presentation. On slide 1, type your name. On slide 2,
record the occupation title, occupation code (shown in the form xx-xxxx), mean
hourly wage, and annual mean wage of your chosen career. If one of these
amounts is missing, calculate it. Assume working 40 h/week for 52 weeks. Then
summarize the duties of an employee with this job. Do not copy the description
from the website word for word.
Project Writing
1. Complete Lesson Checkpoint: Paycheck Deductions, an online,
ungraded assessment. You’ll practice calculating Social Security and Medicare
taxes—a skill essential to completing your project. Reach out to your teacher
with any questions you have after taking this assessment.
2. Open your presentation. On slide 3, complete the pay stub.
(a) Choose a pay period. Choose weekly, biweekly, semimonthly, or
monthly. Then choose if the job is paid by hourly wages or by a given salary.
Complete the first sentence on the slide.
(b) Use the mean wages on slide 1 to calculate the gross pay for
your chosen pay period. On the slide, briefly show or explain how you
determined this amount. For example, multiply the hourly wage by 40, or divide
the annual wage by the appropriate number of pay periods. (Note: Assume 40 hours if working an hourly wage.) Fill in the gross
pay amount on the pay stub under Gross Pay.
(c) Use the gross pay amounts and the table below to determine the
amount of federal income tax withheld. (Note:
This table estimates a typical
withholding amount for a single employee with no dependents. Actual federal
withholding amounts in the real world will differ.)
Annual Gross Income
Federal Income Tax
Withheld
Over $10,000 and up to $20,000
6% of gross pay
Over $20,000 and up to $40,000
10% of gross pay
Over $40,000 and up to $60,000
12% of gross pay
Over $60,000 and up to $80,000
16% of gross pay
Over $80,000 and up to $100,000
18% of gross pay
Over $100,000 and up to $120,000
20% of gross pay
Over $120,000 and up to $140,000
21% of gross pay
Over $140,000 and up to $160,000
22% of gross pay
Over $160,000 and up to $200,000
23% of gross pay
Over $200,000
25% of gross pay
Fill in the amount
withheld for federal tax on the pay stub next to Federal Tax.
(d) Use the gross pay amount to calculate the Social Security and
Medicare taxes. Fill in these amounts on the pay stub.
(e) Use the gross pay amount to determine the state tax. Some states
have no income tax. The tax rates for states that do have an income tax vary.
For this project, assume a 3% state income tax.
(f) Find the total of the taxes. Fill in the total tax amount on the
pay stub under Tax Deductions.
(g) Use the list below to choose voluntary deductions. (Note: This table gives sample amounts
only. Actual deductions in the real world will differ.) Choose at least two of
these deductions.
·
Retirement: Calculate 5% of
gross pay.
·
Health Insurance: Use an
annual deduction of $1650 to calculate the deduction for the pay period.
·
Life Insurance: Use an
annual deduction of $400 to calculate the deduction for the pay period.
·
Disability Insurance: Use
an annual deduction of $150 to calculate the deduction for the pay period.
Fill in the
calculated amounts on the pay stub. Fill in $0 for deductions not chosen.
(h) Find the total of the voluntary deductions. Fill in the total
amount of voluntary deductions on the pay stub under Voluntary Deductions.
(i) Determine the net pay by subtracting the tax deductions and the
voluntary deductions from the gross pay. Fill in the net pay on the pay stub
under Net Pay.
3. Open your presentation. On slide 4, complete the W-2.
(a) Box 1: Enter the annual mean wage by multiplying the gross pay
on your pay stub by the appropriate number of pay periods.
(b) Box 2: Enter the total amount of federal income tax withheld for
a full year by multiplying the amount of federal tax withheld on your pay stub
by the appropriate number of pay periods.
(c) Box 3: Social Security taxes are taken only up to a certain
amount of pay, and this amount changes every year. For the purpose of this
project, use $120,000 as the limit.
·
If the amount in Box 1 is
less than or equal to $120,000, then enter the amount in Box 1 into Box 3.
·
If the amount in Box 1 is
greater than $120,000, then enter $120,000 into Box 3.
(d) Box 4: Enter the total amount of Social Security tax withheld,
which is 6.2% of the amount in Box 3.
(e) Box 5: Enter the annual mean wage, from slide 1. (Notes: Unlike Social Security, there is
no limit on how much Medicare tax is taken out. Also, in the real world, this
amount can be larger than the amount in Box 1 if your employer contributed
money to your retirement plan.)
(f) Box 6: Enter the total amount of Medicare tax withheld, which is
1.45% of the amount in Box 5.
(g) Box 13: If you chose retirement as a voluntary deduction on your
pay stub, then type an X in the appropriate spot.
(h) Box 16: Enter the amount in Box 1.
(i) Box 17: We are assuming a 3% state income tax, so enter 3% of
the amount in Box 16 into Box 17.
Note: For the purpose of this project,
ignore the shaded boxes. In the real world, you may see some of these boxes
filled in.
4.
Open your 1040
spreadsheet, which you saved with your name. In the 1040 tab, part of a blank
1040 is shown on the left. Instructions for filling out the 1040 are shown on
the right. Follow all those instructions, in order. Tax Tables and Tax Formulas
are given in the other two tabs of the spreadsheet. Round all values to the
nearest whole dollar. You do not need to show dollar signs on this form. Save your work when you are finished. You
will submit this document along with your presentation.
5. Open your presentation. On slide 5, type in the following
information from your 1040, and then write the final statement about whether an
employee with this 1040 would receive a refund or owe money, and give the
amount that the person would receive or pay.
·
Total income (from Line 22)
·
Adjusted gross income (from
Line 37)
·
Taxable income (from Line
43)
·
Tax (from Line 44)
·
Total payments (from Line
72)
·
The amount overpaid (from
Line 73) or underpaid (from Line 76)
Project Reflection
1. Go back to the website for the U.S. Bureau of Labor Statistics
and select the link for the occupation you chose. Scrolling down, you will find
maps and tables with employment levels and mean pay rates for states and
localities. Look through this information.
·
Each map has a key that
shows what the different colors on that map represent.
·
The location quotient
indicates the job concentration within a given area. The greater the location
quotient, the greater the concentration of jobs in that area.
2. Open your presentation. On slide 6, write a discussion that
addresses each of the following for your chosen job:
·
Which areas of the United
States have the highest levels of employment? Which areas have the lowest
levels of employment? Why do you think this might be?
·
Which areas of the United
States have the greatest mean pay? Which areas have least mean pay? Do you find
any of this surprising? Why or why not?
·
Use your research to
answer: If someone who wanted this job could move anywhere in the United
States, where would you suggest the person move to and why?

WEEK 6 Assignment: Testing Hypotheses for Means
Assignment: Testing Hypotheses for MeansThis week you have explored three different approaches to t tests. By this point, you know that each test has assumptions about the data and type of research questions it can answer. For this Assignment, you will be provided with three scenarios. As you read the scenarios, be sure and think about aligning the appropriate t test with the question. Consider whether the data are independent samples and if two samples are being compared.To prepare for this Assignment:Review the Learning Resources and the media programs related to t tests.For additional support, review the Skill Builder: Research Design and Statistical Design and the Skill Builder: Hypothesis Testing for Independent Samples t-test, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.Also, review the t test scenarios found in this week’s Learning Resources and consider the three different approaches of t tests:Independent sample t testPaired sample t testOne sample t testBased on each of the three research scenarios provided, open the High School Longitudinal Study dataset or the Afrobarometer dataset from this week’s Learning Resources using SPSS software, then choose and run the appropriate t test.Once you perform your t test analyses, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 2 to 3-paragraph analysis of your t test results for each research scenario and include the SPSS syntax and output. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1SES. Do not forget to evaluate if the t test assumptions are met, justify the selection of type of t test, and report the effect size. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research questions, and output.
