Student Debt – Vermont: The average student loan debt of a U.S. college student at the end of 4 years of college is estimated to be about $22,500. You take a random sample of 136 college students in the state of Vermont and find the mean debt is $23,500 with a standard deviation of $2,600. We want to construct a 90% confidence interval for the mean debt for all Vermont college students.
(a) What is the point estimate for the mean debt of all Vermont college students?
(b) What is the critical value of t (denoted
tα/2) for a 90% confidence interval?
Use the value from the table or, if using software, round
to 3 decimal places.
tα/2 =
(c) What is the margin of error (E) for a 90%
confidence interval? Round your answer to the nearest whole
dollar.
E = $
(d) Construct the 90% confidence interval for the mean debt of
all Vermont college students. Round your answers to the
nearest whole dollar.
< μ <
(e) Based on your answer to (d), are you 90% confident that the mean debt of all Vermont college students is greater than the quoted national average of $22,500 and why?
Yes, because $22,500 is below the lower limit of the confidence interval for Vermont students
.No, because $22,500 is above the lower limit of the confidence interval for Vermont students.
Yes, because $22,500 is above the lower limit of the confidence interval for Vermont students.
No, because $22,500 is below the lower limit of the confidence interval for Vermont students.
(f) We are never told whether or not the parent population is normally distributed. Why could we use the above method to find the confidence interval?
Because the sample size is greater than 30.
Because the sample size is less than 100.
Because the margin of error is less than 30.
Because the margin of error is positive.

The North Store has consistently shown losses over the past two years. For this reason, management is giving consideration to closing the store. The company has asked you to make a recommendation as to whether the store should be closed or kept open. The following additional information is available for your use:

The lease on the building housing the North Store can be broken with no penalty.
The fixtures being used in the North Store would be transferred to the other two stores if the North Store were closed.
The general manager of the North Store would be retained and transferred to another position in the company if the North Store were closed. She would be filling a position that would otherwise be filled by hiring a new employee at a salary of $10,000 per quarter. The general manager of the North Store would continue to earn her normal salary of $11,000 per quarter. All other managers and employees in the North store would be discharged.
The company has one delivery crew that serves all three stores. One delivery person could be discharged if the North Store were closed. This person’s salary is $4,100 per quarter. The delivery equipment would be distributed to the other stores. The equipment does not wear out through use, but does eventually become obsolete.
The company pays employment taxes equal to 15% of their employees' salaries.
One-third of the insurance in the North Store is on the store’s fixtures.
The “General office salaries” and “General office—other” relate to the overall management of Superior Markets, Inc. If the North Store were closed, one person in the general office could be discharged because of the decrease in overall workload. This person’s compensation is $5,500 per quarter.
Required:
1. How much employee salaries will the company avoid if it closes the North Store?
2. How much employment taxes will the company avoid if it closes the North Store?
3. What is the financial advantage (disadvantage) of closing the North Store?
4. Assuming that the North Store's floor space can’t be subleased, would you recommend closing the North Store?
5. Assume that the North Store's floor space can’t be subleased. However, let's introduce three more assumptions. First, assume that if the North Store were closed, one-fourth of its sales would transfer to the East Store, due to strong customer loyalty to Superior Markets. Second, assume that the East Store has enough capacity to handle the increased sales that would arise from closing the North Store. Third, assume that the increased sales in the East Store would yield the same gross margin as a percentage of sales as present sales in the East store. Given these new assumptions, what is the financial advantage (disadvantage) of closing the North Store?

Assume the following facts based on the Jennings case study: Agristar, the successor company to Agriprocessor Inc., has decided to sell the meat packing plant. Your client, Agriprofit, has asked your consulting firm to evaluate the wisdom of acquiring the company. Specifically, as the case study indicates, the plant requires a large employee base of unskilled workers and the previous owners had not been able to hire enough employees without resorting to hiring alien workers. Agriprocessor got into trouble after the workers requested jobs for their minor children to increase household income. Agriprofit has no intention of hiring minors to work in the plant or undocumented aliens but papers can be forged and sometimes, the company must look the other way to meet its production quotas. Given the federal government's inability to resolve the problem of illegal immigration and the Supreme Court's decision in Arizona vs. U.S., which limits a state's ability to pass legislation to resolve the issues inside of its own state borders due to the Supremacy Clause, companies that require unskilled workers have little legal guidance and a lot of criminal and civil exposure if the company's workforce violates immigration and employment laws and regulations. Illegal workers have a different perspective. Many are grateful for employment but pay the price of abusive working conditions. These workers cannot behave as organized labor, in the traditional sense, because they do not wish to be deported.
What would you advise the client to acquire the company or not and the reasons for your recommendations?

Please completely answer the below Biostatistic question.
Hurricanes Rita and Katrina caused flooding of large parts of New Orleans, leaving behind large amounts of new sediment. Before the hurricanes, the soils of New Oleans were known to have high concentrations of lead, a dangerous toxin capable of creating potential health hazard. Zaharan et al. (2010) were interested in the human health impacts of the flood and so measured lead concentrations of blood (in ug/dl) of children who lived in 46 different affected areas both before and after the floods. Complete the responses for the following R outputs.
