Textbook Question
Chapter 9.4, Problem 9.62ACI
Stress in cows prior to slaughter. What is the level of stress (if any) that cows undergo prior to being slaughtered? To answer this question, researchers designed an experiment involving cows bred in Normandy. France (Applied Animal Behaviour Science, June 2010). The heart rate (beats per minute) of a cow was measured at four different pre-slaughter phases—(1) first phase of visual contact with pen mates. (2) initial isolation from pen mates for prepping, (3) restoration of visual contact with pen mates, and (4) first contact with human prior to slaughter. Data for eight cows (simulated from information provided in the article) are shown in the accompanying table. The researchers analyzed the data using an analysis of variance for a randomized block design. Their objective was to determine whether the
- a. Identify the treatments and blocks for this experimental design.
- b. Conduct the appropriate analysis using a statistical software package. Summarize the results in an ANOVA table.
- c. Is there evidence of differences among the mean heart rates of cows in the four pre-slaughter phases? Test using α = .05.
- d. If warranted, conduct a multiple comparisons procedure to rank the four treatment means. Use an experimentwise error rate of α = .05.

A researcher investigated whether a father's level of optimism was predictive of his son's optimism as a young adult. Twenty (20) fathers and sons who agreed to participate in the study were administered a scale measuring their current level of optimism (the scale ranged from 10 to 50), with higher scores indicating greater optimism.
Exercise 3.13 —*** Challenging Question ✶✶✶.
Two women, Anna and Bess, claim to be the legal owners of a diamond ring that -
each claims - has great sentimental value. Neither of them can produce evidence of
ownership and nobody else is staking a claim on the ring. Judge Sabio wants the ring to
go to the legal owner, but he does not know which of the two women is in fact the legal
owner. He decides to proceed as follows. First he announces a fine of $F > 0 and then
asks Anna and Bess to play the following game.
Move 1: Anna moves first. Either she gives up her claim to the ring (in which case
Bess gets the ring, the game ends and nobody pays the fine) or she asserts her claim, in
which case the game proceeds to Move 2.
Move 2: Bess either accepts Anna's claim (in which case Anna gets the ring, the game
ends and nobody pays the fine) or challenges her claim. In the latter case, Bess must
put in a bid, call it B, and Anna must pay the fine of $F to Sabio. The game goes on to
Move 3.

xt:Bong-Cha is deciding what to do during the 30-minute break between her college classes. One rule she could follow is, "Choose the activity with the highest value" (A). Another rule she could follow is, "Choose the activity with the lowest opportunity cost" (B). Do you think Bong-Cha's choice if she follows rule (A) will be the same as the choice she would make if she followed rule (B)? [another way to think about it, "Is rule (A) identical to rule (B) in a sense that they would both induce the same choice?"].

- 7. Some years ago, a new brand of toothpaste was introduced in the United States. According to its advertisements, studies showed that it had "considerable success" in improving the health of a person's teeth. Suppose that these studies were designed in the following way. The manufacturer of this toothpaste chose three samples of seven people; the first sample agreed to use the new brand, the second sample used Brand A, and the third sample used Brand B. After six months, a dentist examined each person's teeth and scored the health of his or her teeth on a scale of 0 (lowest possible score) to 100 (highest possible score). The results were as follows: New Brand Brand A Brand B 65 58 54 71 60 38 53 63 43 55 90 61 34 95 94 82 89 96 77 62 82 The manufacturer of the new toothpaste says that the average score for the new brand is 2 points higher than for Brand A and 4 points higher than for Brand B. Would you agree with the manufacturer's advertisements?

An A-B split was used to divide the company’s 120,000-customer mailing list into two groups. Customers in the control group were sent catalogs listing oxford shirts at their usual price of $40. Customers in the test group were sent catalogs listing the price of oxford shirts at $32.80. During the period of the test, customers in the control group purchased 700 oxford shirts, and customers in the test group purchased 889 oxford shirts. What is the independent variable in this sales experiment? What is the dependent variable in this sales experiment? What is the percent change in price in this experiment? What is price elasticity indicated by the results of this experiment.arrow_forwardAllegiant Airlines is considering an overbooking policy for one of its flights. The airplane has 50 seats, but Allegiant is considering accepting more reservations than seats because sometimes passengers do not show up for their flights, resulting in empty seats. The PassengerAppearance worksheet in the file Overbooking contains data on 1,000 passengers showing whether or not they showed up for their respective flights. In addition, Allegiant has conducted a field experiment to gauge the demand for reservations for the current flight. During this experiment, they did not limit the number of reservations for the flight to observe the uncensored demand. The following table summarizes the result of the field experiment. No. of Reservations Demanded Probability 48 0.05 49 0.05 50 0.15 51 0.30 52 0.25 53 0.10 54 0.10 Suppose Allegiant receives a marginal profit of $108 for each passenger who books a reservation (regardless of whether they show up).

- We have a random sample of workers from a large firm. In 2017, the firm ran a training program. Some workers did the training program, others did not. The firm now wants to assess the effect of the training on earnings. We use the following model to estimate the effect of a training program on annual earnings in 2018: ln(earn2018)=β0+β1train+β2ln(earn2016)+β3educ+β4exper+u where earn2018 = individual total annual earnings in 2018 in dollars train = a dummy variable that takes the value 1 if the individual worker did the training in 2017 and 0 otherwise earn2016 = individual total annual earnings in 2016 in dollars educ = the individual's years of education exper = the individual's years of experience Now, I want to test whether the effect of an additional year of education increases earnings by twice as much as an additional year of experience.

Wine scores range from 0 to 100, with a score of 95 – 100 indicating a great wine, 90 – 94 indicating an outstanding wine, 85 – 89 indicating a very good wine, 80 – 84 indicating a good wine, 75 - 79 indicating a mediocre wine, and below 75 indicating that the wine is not recommended.

(1982) report on a drug designed to reduce hypertension (high blood pressure). Such hypotensive drugs are frequently effective but are also linked to side effects like irritability and a decline in energy. Seventy-five patients with mild hypertension were put on hypotensive drugs and their progress was monitored by doctors and spouses. When asked to rate the treated patients as improved, worse, or unchanged, the doctors rated all 75 patients as "improved." Meanwhile, the spouses rated 74 of the 75 patients as "worse." Why might spouses and doctors differ in their opinion about the effect of going on blood pressure medication?arrow_forward
- Investigators enrolled 2,100 women in a study and followed them monthly to determine the incidence rate of heart disease. After one month of the first period of observation, none had a new diagnosis of heart disease, but 100 had died. In the second observation period which lasted for three months, 1 had a new diagnosis of heart disease within 1 month, and another 99 died within 2 months. In the third observation period which lasted for four months, another 7 had new diagnoses of heart disease and 793 died within 2 months. Calculate the incidence rate of heart disease among this cohort.

When Annika's income rises to $120 per week, she buys 10 boxes of pancake mix and 10 rounds of golf.
