Chapter 9.3, Problem 9.46ACI

Study of recall of TV commercials. Refer to the Journal of Applied Psychology (June 2002) completely randomized design study to compare the mean commercial recall scores of viewers of three TV programs, presented in Exercise 9.28 (p. 520). Recall that one program had a violent content code (V) rating, one had a sex content code (S) rating, and one was a neutral TV program. Using Tukey’s method, the researchers conducted multiple comparisons of the three mean recall scores.

  1. a. How many pairwise comparisons were made in this study?
  2. b. The multiple comparison procedure was applied to the data and the results are shown in the Minitab printout at the top of the next page. An experimentwise error rate of .05 was used. Locate the confidence interval for the comparison of the V and S groups. Interpret this result practically.
  3. c. Repeat part b for the remaining comparisons. Which of the groups has the largest mean recall score?
  4. d. In the journal article, the researchers concluded that “memory for [television] commercials is impaired after watching violent or sexual programming.” Do you agree?

A U.S. study published in The American Journal of Preventive Medicine compared state-level prevalence of firearm ownership in 2002 with state-level rates of firearm assault and firearm robbery in the subsequent year. The investigators found a positive association - meaning that states with higher prevalence of firearm ownership also tended to be the states with higher rates of firearm assault. Which design best describes this study?    a)Observational cohort study  b)Randomized trial c)Case-control study  d)Ecological study
Whirling disease is a deadly disease that affects trout in Montana riversIn a follow-up to a 2006 study conducted by the Montana Department of FishWildlife and Parks (FWP)researchers sought to determine if the proportion of trout afflicted by whirling disease in the Gallatin river differs between rainbow trout and brown trout. To test this theory, researchers collected a representative sample of 527 rainbow trout and 459 brown trout. Of the 527 rainbow trout collected, 120 had developed whirling disease; of the 459 brown trout collected, 74 had developed whirling disease Calculate the relative risk of whirling disease for rainbow trout compared to brown trout in this sample.
In​ randomized, double-blind clinical trials of a new​ vaccine, children were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second​ dose, 116 of 651 subjects in the experimental group​ (group 1) experienced fever as a side effect. After the second​ dose, 73 of 532 of the subjects in the control group​ (group 2) experienced fever as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced fever as a side effect than subjects in group 2 at the α=0.10 level of​ significance? #1 Find the test statistic for this hypothesis test.
