Explanation & Answer
First you need to calculate the (estimated) mean, which is:
mean = sum (P(x) * x) for all x. Here we have:
mean = 23*0.05 + 34*0.44 + 45*0.19 + 56*0.11 + 67*0.21
= 44.89
Now we can find the variance, which is the sum of squares of the distance to the mean:
variance = 0.05*(23-44.89)^2 + 0.44*(34-44.89)^2 + 0.19*(45-44.89)^2 + 0.11*(56-44.89)^2 + 0.21*(67-44.89)^2
= 192.3779
So the standard deviation is sqrt(variance) = 13.87

Northern Virginia Community College Paying Extra Principal on a Mortgage Case Study
Ive provided the worksheet as well as the directions attached to this!Procedure:In our brief case study, we assume the Thomas and Jefferson families have identical mortgages (30-year term, fixed-rate 6% APR, and a loan amount of $175,000). The Thomas family will not pay extra but the Jeffersons will. Follow the steps below prior to your analysis.1.Using the Payment mini calculator of the Financial Toolboxes spreadsheet, calculate the mortgage payment (the same for both families).2.Assume that the Thomas’s will make only the required mortgage payment. The Jeffersons, however, would like to pay off their loan early. They decide to make the equivalent of an extra payment each year by adding an extra 1/12 of the payment to the required amount.Calculate the following to find what they plan to pay each month:a.1/12 of the required monthly payment b.Jeffersons monthly payment found by adding this 1/12 to the required payments3.The Thomas’s will take the full 30 years to pay off their loan, since they are making only the required payments. The Jefferson’s extra payment amount, on the other hand, will allow them to pay off their loan more rapidly. Use the Years mini financial calculator of the Financial Toolbox spreadsheet to calculate the approximate number of years (nearest 10th) it would take the Jeffersons to pay off their loan.

ssignment 1: Bottling Company Case Study
Due Week 10 and worth 140 points
Imagine you are a manager at a major bottling company. Customers have
begun to complain that the bottles of the brand of soda produced in
your company contain less than the advertised sixteen (16) ounces of
product. Your boss wants to solve the problem at hand and has asked you
to investigate. You have your employees pull thirty (30) bottles off the
line at random from all the shifts at the bottling plant. You ask your
employees to measure the amount of soda there is in each bottle. Note:
Use the data set provided by your instructor to complete this
assignment. Write a two to three (2-3) page report in which you:
Calculate the mean, median, and standard deviation for ounces in the bottles.
Construct a 95% Confidence Interval for the ounces in the bottles.
Conduct a hypothesis test to verify if the claim that a bottle
contains less than sixteen (16) ounces is supported. Clearly state the
logic of your test, the calculations, and the conclusion of your test.
Provide the following discussion based on the conclusion of your test:
a. If you conclude that there are less than sixteen (16) ounces in a
bottle of soda, speculate on three (3) possible causes. Next, suggest
the strategies to avoid the deficit in the future.
Or
b. If you conclude that the claim of less soda per bottle is not
supported or justified, provide a detailed explanation to your boss
about the situation. Include your speculation on the reason(s) behind
the claim, and recommend one (1) strategy geared toward mitigating this
issue in the future.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size 12), with
one-inch margins on all sides. No citations and references are
required, but if you use them, they must follow APA format. Check with
your professor for any additional instructions.
Include a cover page containing the title of the assignment, the
student’s name, the professor’s name, the course title, and the date.
The cover page and the reference page are not included in the required
assignment page length.
The specific course learning outcomes associated with this assignment are:
Calculate measurements of central tendency and dispersal.
Determine confidence intervals for data.
Describe the vocabulary and principles of hypothesis testing.
Discuss application of course content to professional contexts.
Use technological tools to solve problems in statistics.
Write clearly and concisely about statistics using proper writing mechanics.

unit 8. anova
Design a study you would like to explore in your future or current career that could be analyzed with ANOVA. To help design the study, please answer the following:
What is the independent variable? What are your levels of the independent variable?
What is the dependent variable?
What do you expect to find if you ran the study? Please list this out both in statistical language (feel free to make up some numbers for the results) as well as real-world language.
What would you expect to find with post hoc analyses? Which groups might be significantly different from which other groups?
