User generated content is uploaded by users for the purposes of learning and should be used following Studypool's honor code & terms of service.
Explanation & Answer
V - 4/5 = 3 1/3
V = 3 + 1/3 + 4/5
= 3 + 5/15 + 12/15 (multiply top and bottom by 5 and other one by 3 to get LCM=15)
= 3 17/15
= 3 + 1 2/15 (because 17/15 = 1 and 2/15)
=4 2/15

Saving for Retirement, math homework help
I will attach two examples when you bid to paraphrase Unit Project: Saving for RetirementReview the requirements for completing the Graded Assignment.GOALSSome people say that compound interest is the eighth wonder of the world. During this unit, you will see why compound interest is so highly thought of.First you’ll find the entry-level salary for a career of your choosing. Then you’ll calculate and compare how much money an employee with this starting salary can have in his or her retirement account under different scenarios. Lastly, you’ll determine what percent of that person’s gross salary must be saved to meet certain financial goals.TEMPLATE1. Download the project template and rename the file as RetirementPresentation_YourName. This file will become your presentation.2. Download the spreadsheet template and rename the file as Spreadsheet_YourName. You will use this file to help you create your presentation.PROJECT RESEARCH1. Look on the Internet for the entry-level salary, sometimes called the starting salary, of a career that you are interested in.(a) If you have a certain career in mind, include the career name in your search. For example, you could enter entry-level salary of a police officer or average starting salary of a journalist in the search bar.(b) You could also look at websites that list salaries for all kinds of careers. Enter entry-level salary information, or starting salary information, in the search bar.(c) You may need to enter your ZIP code for results. Skip over any websites that require payment for information or want your specific contact information.(d) If you find a range for the average salary, but not necessarily the starting salary, then choose the lower end of the range as the starting salary.2. Open your presentation. On slide 1, type your name. On slide 2, complete the table.(a) If you are given an hourly salary, assume working 40 h/week for 52 weeks to calculate the annual salary.(b) Determine the monthly salary by dividing the annual salary by 12.PROJECT WRITING1. Complete Lesson Checkpoint: Percents and Interest, an online, ungraded assessment. You’ll practice solving percent problems and calculating compound interest—skills essential to completing your project. Reach out to your teacher with any questions you have after taking this assessment.2. Open your spreadsheet. Make sure that you are in the Worksheet tab. This worksheet approximates the total amount in a retirement account for different numbers of years, assuming a 7% rate of return, compounded monthly.Assume that an employee with the starting salary you listed on slide 2 has 5% of his or her gross monthly paycheck amount deposited into a retirement account. In cell B3, enter 5% of this gross monthly salary. Other cells will automatically populate. These cells have formulas in them. Do not change these formulas.Notice the following.· Each row, starting with Row 3, represents a year.· Amounts for up to 40 years are shown. You may need to scroll down to see them.· The monthly deposits for each year increase. That increase is for yearly raises and promotions.· The total amount in the account at the end of each year is in Column N. You may need to scroll right to see it.· The total amount the employee contributed into the account during a given year is in Column P. The total amount he or she contributed from Year 1 up to that year is in Column Q.· A bar graph that shows the total amount in the account at the end of each year is in the Graph tab. This graph automatically updates upon entering an amount in cell B3.3. Open your presentation. Complete slide 3.(a) Complete the table. The total contribution after 40 years is in cell Q42. The total amount in the account after 40 years is in cell N42.(b) Insert an image of the bar graph.4. Complete slide 4, which compares how much the employee would have saved up by the retirement age of 65 if he or she started contributing at different ages.(a) First record the monthly deposit amounts (from Column B) for each given age below.It is important that you copy these amounts now, because you will be changing the spreadsheet.Monthly Deposit AmountAge 25 (Year 1: cell B3)Age 35 (Year 11: cell B13)Age 45 (Year 21: cell B23)(b) You can complete the first row of the table in slide 4 by copying the amounts from your table on slide 3. This represents 40 years of saving.(c) Suppose an employee starts saving at age 35 instead. The first monthly deposit will be what you recorded in the second row of the table above. Enter that amount in cell B3. Because the employee will retire at 65, he or she will save for a total of only 30 years. Complete the second row of the table in slide 4 by copying the new amounts in cells Q32 and N32 from your spreadsheet.(d) Now suppose an employee starts saving at age 45 instead. The first monthly deposit will be what you recorded in the last row of the table above. Enter that amount in cell B3. Because the employee will retire at 65, he or she will save for a total of only 20 years. Complete the third row of the table in slide 4 by copying the new amounts in cells Q22 and N22 from your spreadsheet.(e) Write a brief discussion about how the amounts in the table in slide 4 compare. Include in your discussion whether you found any of the results surprising.5. Open your spreadsheet. In the Worksheet tab, change the amount in cell B3 back to the monthly deposit amount for an employee who begins saving 5% of gross monthly pay at age 25. This is the amount you recorded in the first row of the table in Step 4a above.6. Open your presentation. Complete slide 5, which compares other possible scenarios.(a) Assume an employee starts saving for retirement at age 25, but stops making contributions after 10 years. The employee just lets the total amount in the account after 10 years gain interest for another 30 years. Find the total amount in the account after those 30 years by using the compound interest formula, where:· P is the total amount in the account after 10 years of saving. This is the amount in cell N12.· r is the rate of return. For this project, r = 0.07.· n is the number of compounding intervals per year. For this project, n = 12.· t is the number of years, so t = 30.Complete the first row of the table. (The amount contributed is what you used for the principal.)(b) The second row in the table represents an employee who started saving 5% of gross pay at age 35 and continued to save for the next 30 years. You can copy these amounts from the table on slide 4.(c) In your spreadsheet, change the amount in cell B3 to the first monthly deposit amount for an employee who begins saving 10% of gross monthly pay at age 45. That is twice the amount you recorded in the last row of the table in Step 4a above. Because the person saves only for 20 years, use the amounts in cells Q22 and N22 to complete the third row in the table.(d) Write a brief discussion about your findings. Include in your discussion whether you found any of the results surprising.7. Open your spreadsheet. Continue to change the amount in cell B3, and check the amount in cell N42, until you have determined the smallest first year’s monthly deposit, in whole dollar amounts only, that an employee can deposit into his or her retirement account to have at least each of the following amounts of money saved up after 40 years. Then calculate what percent of gross pay that is. (Use the monthly salary from slide 2 of your presentation.) Record your percents here so that you can refer to them in the next step.Retirement GoalAmountPercentAt least $250,000At least $750,000At least $1,000,0008. Open your presentation. On slide 6, complete the table. Then write a brief discussion that tells whether and why it is reasonable to expect someone who earns the salary on slide 2 to have a million dollars in an account at retirement time.PROJECT REFLECTION1. Join the online session set up for you and your classmates.2. Write a response to any of the following.· Suppose you are talking to both a recent college graduate who does not have much money in his budget for retirement savings and a 40-year-old employee who never opened a retirement account for herself until now. How would the retirement advice you give to each of them differ?· If you were considering an offer of employment, how much of a factor would the employer’s retirement package make in your decision? Why?· The Social Security Administration might want to raise the full retirement age for people born in the year 2000 or later. Why do you think the agency might want to do that? Do you think it would be fair? If so, what would be a fair age? If you don’t think it would be fair, why not?3. Comment on at least one other student’s post.Alternate Reflection AssignmentIf your teacher excuses you from the online discussion, then add a slide (slide 7) to the end of your presentation. On the slide, consider these two general savings strategies:1. Begin saving a small amount at a young age.2. Begin saving a large amount of money at an older age.Name possible pros and cons of each strategy. Tell which strategy you think might be best for you and why.SUBMISSIONConfirm that your project contains all your work:· Salary information· Overall look at the retirement account (amounts and bar graph)· Starting-age comparisons (amounts and discussion)· Other comparisons (amounts and discussion)· Reaching certain goals (amounts and discussion)· Alternate reflection assignment slide (ONLY if you did not participate in the online discussion)Submit your project to your teacher.

Springdale SHopping Survey
Instructions The major shopping areas in the community of Springdale include Springdale Mall, West Mall, and the downtown area on Main Street. A telephone survey has been conducted to identify strengths and weaknesses of these areas and to find out how they fit into the shopping activities of local residents. The 150 respondents were also asked to provide information about themselves and their shopping habits. The data are provided in the file SHOPPING. The variables in the survey can be found in the file CODING.In this exercise, some of the estimation techniques presented in the module will be applied to the Springfield Shopping survey results. You may assume that these respondents represent a simple random sample of all potential respondents within the community, and that the population is large enough that application of the finite population correction would not make an appreciable difference in the results.Managers associated with shopping areas like these find it useful to have point estimates regarding variables describing the characteristics and behaviors of their customers. In addition, it is helpful for them to have some idea as to the likely accuracy of these estimates. Therein lies the benefit of the techniques presented in this module and applied here.1.Item C in the description of the data collection instrument lists variables 7, 8, and 9, which represent the respondent’s general attitude toward each of the three shopping areas. Each of these variables has numerically equal distances between the possible responses, and for purposes of analysis they may be considered to be of the interval scale of measurement.1.Determine the point estimate, and then construct the 95% confidence interval for μ7 = the average attitude toward Springdale Mall.2.Repeat part (a) for μ8 and μ9, the average attitudes toward Downtown and West Mall, respectively.2.Given the breakdown of responses for variable 26 (sex of respondent), determine the point estimate, and then construct the 95% confidence interval for p26 = the population proportion of males.3.Given the breakdown of responses for variable 28 (marital status of respondent), determine the point estimate, and then construct the 95% confidence interval for p28 = the population proportion in the “single or other” category.4.Assume the managers have requested estimates of the mean attitudes towards each mall with a margin of error of 0.05 for each. If the managers want to have 95% confidence that the sample mean will fall within this margin of error, how large should the sample size be for each mall?RequirementsMust answer questions in detailMust include Excel Worksheet that proves work!

Week 5 : Hypothesis Testing (continued)
Open the small Excel database that was provided to you in week 4. To run the test statistics you have to re-arrange your data.
With this database, you will:
Run a one-way ANOVA to compare three or more groups of people (specified by a categorical variable) on one continuous variable.
Write the null and alternate hypotheses.
What is the calculated mean for each group?
What is the calculated F value?
What is the p and critical F value?
Is the p value significant? Is calculated F value greater than Critical F value? Conclusion?
Run a chi-squared test to determine whether one group of people has higher rates of a given outcome relative to the other groups of people in the data set.
Write the null and alternate hypotheses.
What is the calculated chi-square value?
What is the p and critical value?
Is the p value significant? Is calculated chi-square value greater than Critical F value? Conclusion?
