.4 Read the following excerpts from the University of Michigan News Service online article “Women need not lose sleep over menopause,U-M study says” (April 27,2004). ANNARBOR,Mich.—Can’tgetagoodnight’ssleep?Don’tbequicktoblameitonmenopause. Middle-aged women often complain that they sleep poorly,and both women and their health care providers point to menopause as the cause. But University of Michigan researchers Jane Lukacs and Nancy Reame say it may be time to put that assumption to rest.In an article in the justreleased April issue of the Journal of Women’s Health,Lukacs,an assistant research scientist at the U-M School of Nursing, under the direction of nursing professor Reame, tested the connection between the hormone estrogen and women’s sleep quality. Her conclusion:“Estrogen has been blamed for a lot,but that doesn’t seem to be what’s at work here.” To separate aging effects from menopause, Lukacs and her collaborators studied a group of women aged 20–52,and compared them to age-matched women who had gone through menopause, some of whom were using estrogen therapy.For example,she examined a 47-year-old woman still having regular menstrual cycles and compared her data to a 47-year-old woman who had not had regular cycles for 12 months. They found total sleep time,time spent awake during the night,and efficiency of sleep time all were worse for older women than younger women,regardless of whether the older women were still having menstrual cycles and regardless of whether they used estrogen therapy.While young women around age 24 slept about seven hours (416.9 minutes),all women in their 40s,regardless of their estrogen levels or menopause status, got only about six to six-and-a-half hours of sleep (354.9–377.8 minutes). Further, although many women have taken hormone replacement drugs to try to help their sleep,Lukacs and Reame found that for women who were not having hot flashes,there was little difference in sleep between post-menopausal women who were or were not taking estrogen supplements.“Our findings fail to support the popular view that estrogen plays an important role in sleep enhancement,”the article states.“The use of an estrogen patch or gel for three months did not improve any objective measure of sleep architecture.” The research team studied 51 women who participated in an overnight sleep challenge at U-M Hospitals.Women underwent a 24-hour blood sampling protocol to examine their hormone levels and wore electrodes for sleep monitoring from 11 p.m.to 7 a.m.Researchers studied sleep stages, REM sleep and sleep disruption. The researchers noted that because this study involved an in-hospital,one-night sleep observation,further research examining women’s natural sleep patterns in their own homes over multiple nights could give more insight into why women sleep poorly at midlife. They added that in the future,researchers could build on their study and look for such variants as oxygen saturation to look for sleep apnea, leg muscle movement during sleep, and patterns associated with hot flashes,determined by monitoring skin temperature.Hormone replacement therapy might diminish muscle movement during sleep and calm hot flashes,Lukacs said, which could account for some of the beliefs about estrogen improving sleep.

(a) Is this an observational study or an experiment?

(b) What are the explanatory and response variables?Hint:The article states the researcher “tested the connection between the hormone estrogen and women’s sleep quality.”This gives the general variables being linked.However,the article does go on to state some of the specific response variables that were compared. List some of these response variables.

(c) Consider the following hypotheses,tested using a 5% significance level. The use of an estrogen patch or gel for three months does not improve the total sleep time on average. The use of an estrogen patch or gel for three months does improve the total sleep time on average. Basedontheresultsstatedinthearticle,givetwopossiblevaluesforthep-valueofthistest.

(d) Consider the following sentence from the article:“For example,she examined a 47-yearold woman still having regular menstrual cycles and compared her data to a 47-year-old woman who had not had regular cycles for 12 months.”What is this design technique called and why was it done?

(e) What were some of the other possible confounding variables that the researchers suggested might be incorporated into future studies

Students attending a certain university can select from 130 major areas of study. A student's major is identified in the registrar's records with a two-or three-letter code (for example, statistics majors are identified by STA, math majors by MS). Some students opt for a double major and complete the requirements for both of the major areas before graduation. The registrar was asked to consider assigning these double majors a distinct two- or three-letter code so that they could be identified through the student records system.

(a)

What is the maximum number of possible double majors available to the university's students?

double majors

(b)

If any two- or three-letter code is available to identify majors or double majors, how many major codes are available?

codes

(c)

How many major codes are required to identify students who have either a single major or a double major?

codes

(d)

Are there enough major codes available to identify all single and double majors at the university?

Yes

No

John West’s Used Cars plc has always hired students from the local university to wash the cars on the lot. John West is considering the purchase of an automatic car wash that would be used in place of the students. The following information has been gathered by John West’s accountant to help him make a decision on the purchase:
a) Payments to students for washing cars total R15 000 per year at present.
b) The car wash would cost R21 000 installed, and it would have a 10-year useful life. John West uses straight-line depreciation on all assets. The car wash would have a negligible salvage value in 10 years.
c) Annual out-of-pocket costs associated with the car wash would be: wages of students to operate the wash, keep the soap bin full and so forth, R6 300; utilities, R1 800; and insurance and maintenance, R900.
d) John West now earns a return of 20% on the funds invested in his inventory of used cars. He feels that he would have to earn an equivalent rate on the car wash for the purchase to be attractive.
Required
1 ) Determine the annual savings that would be realised in cash operating costs if the car wash was purchased.
2) Calculate the simple rate of return promised by the car wash. (Hint: Note that this is a cost reduction project.) Will John West accept this project if he expects a 20% return?
3) Calculate the payback period on the car wash. John West (who has a reputation for being something of a penny-pincher) will not purchase any equipment unless it has a payback of four years or less. Will he purchase the car wash equipment?
4) Calculate (to the nearest whole per cent) the internal rate of return promised by the car wash. Based on this calculation, does it appear that the simple rate of return would normally be an accurate guide in investment decisions?

A university has 15,000 students. We have drawn a simple random sample size of 400 from the population and recorded how much money each student spent on cellular telephone service during November 2003. For this sample, the sample mean is $36, and sample standard deviation is $20. At a 99% level of confidence, test the null hypothesis that these 15,000 students, combined, did not spend more than $500,000 on cellular telephone service during November 2003.

Ann and Suzan are classmates who graduated with business degrees from Athabasca University. Ann inherited $50,000 from her father. She considers forming a 10-year business partnership with Suzan. To join the partnership, Ann needs to invest $50,000. She believes her portion of the partnership will generate the following profits at a discount rate of 4%.

Year Profits Present Value
1 $2000
2 $4,000
3 $6,000
4 $7,000
5 $8,000
6 $10,000
7 $12,000
8 $14,000
9 $17,000
10 $20,000

a) Calculate the Net Present Value (NPV).

b) Instead of forming a partnership with Suzan, Ann has the option to buy a government bond. Ann expects to receive $150 per year for each of the next ten years, and then receive a principle repayment of $50,000. What is the value of a coupon bond that pays $150 per year for each of the next ten years? Assume the rate is 5%.

c) Suppose Ann has the option to buy a new motor home for $25,000 and sell it for $15,000 after six years. Alternatively, she can lease the motor home for $250 per month for six years and return it at the end of the six years. For simplification, assume that lease payments are made yearly instead of monthly and pay at the beginning of each year. If the interest rate, r, is 3.5%, is it better to lease or buy the motor home?

NAME Resolving Ethical Business Challenges Charlie just graduated from Michigan University and landed a job as a copywriter at Fletcher, Alexander, and Burgess (FAB) Advertising assigned to one of the subsidiary accounts of Delicious Uber Bacon Ingredients Extraordinaire Corporation. This conglomerate was primarily a food processing manufacturer beginning one hundred years ago with pork in the Midwest. Overall corporate sales of beef, chicken, pork, and seafood were more than $ million each year. FAB considered many advertising options and opted for a celebrity spokesperson. That meant Charlie would work with Alice Aimee Lucie Jeanne Bompard as the celebrity endorser. Ms. Bompard is a well-known, well-liked, and vibrant actress with a large younger following. Kelly, President of FAB, asked Charlie to step into her office. “Charlie, this new account is a good start for you. We usually don’t let our new copywriters handle accounts by themselves, but you have proven to be a capable employee. Your job on this account is to write copy for the commercials using Ms. Bompard’s product testimonials. The copy needs to be crafted as a testimonial, targeting the market of seventeen to thirty-year-olds. Ms. Bompard already signed an affidavit as to being a bona fide user of the product. The scripts should feature her testifying to the quality, value, and tastiness of the bacon. I want you to meet her tomorrow so you can start the writing process and understand her personality in order to script the messages. Spend the rest of the day immersing yourself in her biography and researching her on the Internet.” As Charlie left Kelly’s office he remembered a Facebook post about Ms. Bompard being a vegetarian. The next day at their meeting, Charlie asked her if she had actually tasted the bacon. Ms. Bompard replied, “Why yes, technically and legally I have tried Uber. In fact, I’ve been a huge fan since I was a kid. Bacon is my favorite food. I’ve done several testimonials in the past and know the American Advertising Federation (AAF) rules. I know as long as my comments are based on verifiable personal use, the message cannot be challenged as deceptive. In fact, Uber bacon has been a favorite of mine since I was young. It wasn’t until a month ago I became a vegetarian. Eating all that bacon for decades really did a number on my cholesterol.” “So, you feel comfortable about endorsing Uber even though you don’t eat it now?” asked Charlie. “No question about it. As far as bacon goes, Uber is second to none in taste. If people are going to eat bacon, why not eat the best? Even if it is a heart attack waiting to happen,” Ms. Bompard joked. The next day Kelly asked Charlie how it went. He explained their conversation and expressed concern over the fact Ms. Bompard is currently a vegetarian, and she attributed her high cholesterol to Uber bacon. Charlie felt relief when he saw the concern in Kelly’s
face, but soon realized her concern was about Ms. Bompard pulling out of the advertisement. Charlie reassured Kelly Ms. Bompard still wanted to promote the product, but it seemed like a contradiction to have a vegetarian promoting bacon. Kelly responded by saying as long as Ms. Bompard had eaten the bacon at some point in her life and thinks it is a good product, it makes no difference as to whether she currently eats the bacon. She continued, "Sometimes in advertising, you have to add a spin to the message you are communicating so it fits with the product you are selling. Not only are you selling a product, but more importantly, you are selling an experience, a feeling, an idea that appeals to consumers." As Charlie walked home that evening, he wondered how he was going to write this advertisement. He did not want to begin his career in a dishonest manner, but he also wanted to produce work that pleased his boss. He tried to think of creative ways to mask the contradiction of the advertisement. Maybe with humor? He asked himself if this approach would still feel dishonest. The next morning Charlie was going to meet with both Ms. Bompard and Kelly about what he had written thus far.
