A football coach claims that players can increase their strength by taking a certain supplement. To test the
theory, the coach randomly selects 9 athletes and gives them a strength test using a bench press. The results are
listed below. Thirty days later, after regular training using the supplement, they are tested again. The new
results are listed below. Test the claim that the supplement is effective in increasing the athletesʹ strength.
Use α= 0.05. Assume that the distribution is normally distributed.

Use any method, however, follow the PHANTOMS acronym.

A college football coach was interested in whether the college’s strength development class increased his

players’ maximum lift (in pounds) on the bench press exercise.  He asked four of his players to participate

in the study.  The amount of weight they could each lift was recorded before they took the strength

development class.  After completing the class, the amount of weight they could each lift was again

measured.  The data are as follows.  

The coach wants to know if the strength development class makes his players stronger, on average.  Use

an  significance level to test the claim that the mean amount of weight lifted increases after taking

the strength development class.  (Assume that the paired sample data are simple random samples and that

the differences have a distribution that is approximately normal.)

a)  Find the values of  and .

b)  State the hypotheses.   

c)  Calculate the test statistic and specify the critical value.

d)  Find the P-value.

e)  State the initial conclusion regarding the null hypothesis .

f)  State the final conclusion in your own words that addresses the original claim.

Multiple Choice

• All of the other statements describe insider trading.

-Interpret the decision in the context of the original claim.

A weight-lifting coach claims that weight-lifters can increase their strength by taking vitamin E. To test the theory, the coach randomly selects 9 athletes and gives them a strength test using a bench press. Thirty days later, after regular training supplemented by vitamin E, they are tested again. The results are listed below. Use the Wilcoxon signed-rank test to test the claim that the vitamin E supplement is effective in increasing athletes' strength. Use α = 0.05.

You own a chain of 3 dry-cleaning stores in a medium-size town. A problem in customer service has surfaced recently. When you spend the day, or even part of the day in a particular store, clerks seem to provide excellent customer service, spotters are making sure all stains are removed from garments, and pressers are doing a good job of pressing difficult items such as silk blouses. Yet during those same visits, customers complain to you about such things as stains not being removed and items being poorly pressed in some of their previous orders; indeed, several customers have brought garments in to be redone. Customers also sometimes comment on having waited too long for service on previous visits Discuss the extent to which you believe that you have a motivation problem in your stores. 2. Using concepts you have studied in this unit, design a plan to increase the motivation of clerks to provide prompt service to customers even when they are not being watched. 3. Design a plan to increase the motivation of spotters to remove as many stains as possible even when they are not being watched. 4. Design a plan to increase the motivation of pressers to do a topnotch job on all clothes they press, no matter how diff

Delta Sonic is a car wash provider in Western New York. VIP Customers at their Buffalo, NY location sign up for unlimited car washes and a separate line & dedicated car wash services those customers (i.e. a single-server single-queue model). Assume VIP customers arrive every 10 minutes on average and that their inter-arrival time is exponentially distributed. Also, assume that processing (washing) time is the sum of two components:

A constant (i.e. not random) basic washing time that is exactly 4 minutes.

A random extra-service time that is exponentially distributed with mean time of 2 minutes.

In Excel, simulate the arrival times and processing times of VIP customers at this car wash using 2,000 sample customers. Using the results of your simulation, calculate the percentage of VIP customers that were in the process (i.e. waiting+washing) for longer than 12 minutes. Press F9 to rerun your simulation several times and record the results for the percentage of customers who wait longer than 12 minutes. Using the median of these recorded percentages as your estimate of the percentage of customers expected to wait longer than 12 minutes, enter that probability here as a two digit decimal e.g. 0.25, 0.45, 0.99, etc.)

Super Products Inc. has three plants, located at Aville, Bville, and Cville, producing shipments of its new wonder trouser-press which have to be shipped to four retail centers. The plants at Aville, Bville, and Cville produce 12, 17, and 11 shipments of trouser-presses per week, respectively. Each retail center needs to receive 10 shipments per week. The distance from each plant to each retail center in kilometers is as follows:

                                                             Retail Center

                                               1              2              3              4

                          Aville         800         1300         400           700

Plant                  Bville       1100         1400         600         1000

                          Cville         600         1200         800          900

Shipping costs per shipment are $100 plus 25 cents per kilometer. Super Products Inc. wishes to design an optimal shipping plan to minimize costs.

i) Set up an appropriate transportation problem

ii) Determine an initial basic feasible solution using the Vogel Method and then solve the problem using the transportation simplex. Be sure to compute not only the required pattern of shipments but also the actual minimum cost of making them.

iii) How would your solution change if the cost of shipments between Bville and Retail Center 3 became prohibitively expensive? Explain.

Internet giant Zoidle, a U.S. company, generated sales of £2.5 billion in the United Kingdom in 2013 (approximately $4 billion in U.S. dollars). Its net profits before taxes on these sales were £200 million, and it paid £6 million in corporate tax, resulting in a tax rate of 3 percent. The corporate tax rate in the United Kingdom is between 20 percent and 24 percent.

The CEO of Zoidle held a press conference stating that he was proud of his company for taking advantage of tax loopholes and for sheltering profits in other nations to avoid paying taxes. He called this practice “capitalism at its finest.” He further stated that it would be unethical for Zoidle not to take advantage of loopholes and that it would be borderline illegal to tell shareholders that the company paid more taxes than it had to pay because it felt that it should. Zoidle receives significant benefits for doing business in the United Kingdom, including tremendous sales tax exemptions and some property tax breaks. The United Kingdom relies on the corporate income tax to provide services to the poor and to help run the agency that regulates corporations. Is it ethical for Zoidle to avoid paying taxes? Why or why not?

Describe how you would advise the company to act in the following situation. Please be sure to describe your ethical reasoning process.
