Direct mail advertisers send solicitations​ ("junk mail") to thousands of potential customers in the hope that some will buy the​ company's product. The response rate is usually quite low. Suppose a company wants to test the response to a new flyer and sends it to 1110 people randomly selected from their mailing list of over​ 200,000 people. They get orders from 108 of the recipients.

​Create a 90% confidence interval for the percentage of people the company contacts who may buy something.

Western State University (WSU) is preparing its master budget for the upcoming academic year. Currently, 16,500 students are enrolled on campus; however, the admissions office is forecasting a 8 percent growth in the student body despite a tuition hike to $85 per credit hour. The following additional information has been gathered from an examination of university records and conversations with university officials:

• WSU is planning to award 200 tuition-free scholarships.
• The average class has 20 students, and the typical student takes 15 credit hours each semester. Each class is three credit hours.
• WSU’s faculty members are evaluated on the basis of teaching, research, and university and community service. Each faculty member teaches five classes during the academic year.

1.Prepare a tuition revenue budget for the upcoming academic year.

2.Determine the number of faculty members needed to cover classes.

3. Assume there is a shortage of full-time faculty members. Select at least five actions that WSU might take to accommodate the growing student body by selecting an "X" next to the action.

4.You have been requested by the university’s administrative vice president (AVP) to construct budgets for other areas of operation (e.g., the library, grounds, dormitories, and maintenance). The AVP noted: “The most important resource of the university is its faculty. Now that you know the number of faculty needed, you can prepare the other budgets. Faculty members are indeed the key driver—without them we don’t operate.” Are faculty members a key driver in preparing budgets? Yes or No?

Who should decide when a healthcare procedure is medically necessary: the doctor who is treating the patient, or the health insurance company who is paying the bill? What are the moral and ethical issues concerning the insurance company making these decisions, which are driven by cutting healthcare costs and making a profit?

6. Test H₀: 8 versus H_A: > 8, given = 0.01, n = 25, = 8.13 and s = 0.3. Assume the sample is selected from a normally distributed population.

7. Test H₀: π = 0.25 versus H_A: π 0.25 with p = 0.33 and n = 100 at alpha = 0.05 and 0.10.

8. Test at α = 0.01 the hypothesis that a majority (more than 50%) of students favor the plus/minus grading system at a university if in a random sample of 500 students, 285 favor the system?

9. Test whether the sample evidence indicates that the average time an employee stays with a company in their current positions is less than 3 years when a random sample of 64 employees yielded a mean of 2.76 years and s = 0.8. Use = 0.01. Assume normal distribution.

University Printers has two service departments (Maintenance and Personnel) and two operating departments (Printing and Developing). Management has decided to allocate maintenance costs on the basis of machine-hours in each department and personnel costs on the basis of labor-hours worked by the employees in each.

The following data appear in the company records for the current period:

Required:

Allocate the service department costs using the reciprocal method. (Matrix algebra is not required because there are only two service departments.)

Find and analyze an article (first published in the last 28 days) about some topic dealing with nutrition and/or exercise addressing a hypothesis. This can come from a newspaper, magazine or other periodical.Analyze the article and address the following:

1. What hypothesis was tested?

2. How was it tested?

3. Was the hypothesis supported or rejected?

4. Is the sponsor of the science mentioned? This could be a university where research was conducted, a company that supplied funding, etc. Do you think the sponsor may have influenced the science? By that I mean do you think the source of funding could lead to a conflict of interest?

5. What are some implications of this research?

6. What could you do if you wanted to find out more about the topic? Be more specific.
