Chapter 17, Problem 20P
- Cialdini, Reno, andKallgre,n (11990) examined how peo ple conform to norms concerning liner mg. The research
er wanted to determine whether a person ' tendency to litter depended on the amount of litter already in the area. People were handed a handbill as they entered an amusement park. The entrance area had already been prepared with either no litter, a small amount of litter or a lot of litter lying on the ground. The people were
observed to determine whether they dropped their hand bills The frequency data are as follows:
Littering
Amount of Litter Small
Large
None
Amount
Amount
- Do the data indicate that people’s tendency 1to litter depends on the amount of litter already on the ground? That is, is there a significant relationship between littering and the amount of existing litter? Test at the .05 level of significance.

A study examined the link between sodium intake and blood pressure inchildren and adolescents between the ages of 8 and 18. The mean systolicblood pressure (SBP) was 112.8 mm Hg among the 636 study participants whowere overweight or obese and consumed high levels of sodium. Based on thisdata the researchers need to decide if they believe that the mean systolicblood pressure for the group was higher than for other groups.
a. What would be a Type I error in this context? Your answer shouldconsist of both the researchers’ decision and what the reality is.
b. What would be a Type II error in this context? Your answer shouldconsist of both the researchers’ decision and what the reality is.
It is a questionable research practice to identify how many cases are in each level of exposure within your dataset prior to identifying your hypothesis.
A) agree
B) disagree
3. Dentists make many people nervous. To assess any
effect of such nervousness on blood pressure, the
systolic blood pressure of 60 subjects was measured
both in a dental setting and in a medical setting (The
Effect of the Dental Setting on Blood Pressure
Measurement," Amer. J. of Public Health, 1983:1210-
1214). For each subject, the difference between dental
setting pressure and medical setting pressure was
computed; the resulting sample mean difference and
sample standard deviation of the differences were 4.47
and 8.77 mmHg, respectively.
o (a) Estimate the true mean difference
between blood pressures for these two
settings using a 99% confidence level.
o (b) Does it appear that the true mean
pressure is different in a dental setting than
in a medical setting? Explain your reasoning.

One aspect in which the generic drugs might differ is their extent of absorption in the blood. Twelve subjects were available for the study. Six were randomly selected to receive the generic drug first and then, after a washout period, receive the “reference” drug. The remaining six received the “reference” drug first, followed by the generic drug after the washout period. Suppose the t test statistic is t = 1.72. What is the p-value for a two-sided test?

- The National Highway Traffic Safety Administration requires each U.S. state to carry out an observational study to assess the level of seat belt use in the state. One report summarized data from a study done in a certain state. Unfortunately, the "sex" variable provided very little information, and only indicated that it collected the values Female and Male; it may be that this refers to the gender identity of the respondent. The proportions in the accompanying table are based on observations of over 25,000 drivers and passengers. Male Female Uses Seatbelt 0.422 0.452 Does Not Use Seat Belt 0.078 0.048 Assume that these proportions are representative of adults in this state and that an adult from this state is selected at random.

- New research suggests that watching television especially medical shows such as Grey’s Anatomy and House, can result in increased concern about personal health (Ye, 2010). Surveys administrated to college students measure television viewing habits and health concerns such as fear of developing the diseases and disorders seen on television. For the following data, students are classified into three categories based on their television viewing patterns and health concerns are measured on a 10-point scale with 0 indicating “none”. a) Use an ANOVA with = .05 to determine whether there are significant mean differences among the three groups. c) Use Tukey’s HSD test with = .05 to determine which group are significantly different.
