Suppose that 35% of the voters in a state are registered as Republicans, 40% as

Democrats, and 25% as Independents. A newspaper wants to select a sample of 1000

registered voters to predict the outcome of the next election. If it randomly selects 350

Republicans, randomly selects 400 Democrats, and randomly selects 250 Independents,

did this sampling procedure result in a simple random sample of registered voters from

this state?

a. Yes, because each registered voter had the same chance of being chosen.

b. Yes, because random chance was involved.

c. No, because not all registered voters had the same chance of being chosen.

d. No, because a different number of registered voters was selected from each party.

e. No, because not all possible groups of 1000 registered voters had the same chance of

being chosen.

Reporting weight loss A total of 300 people participated in a free 12-week weight-loss

course at a community health clinic. After one year, administrators emailed each of the

300 participants to see how much weight they had lost since the end of the course. Only

56 participants responded to the survey. The mean weight loss for this sample was 13.6

pounds. Describe how nonresponse might lead to bias in this study. Explain the likely

direction of the bias.

Improving response rate -How can we reduce the rate of refusals in telephone surveys? Most people who answer at all listen to the interviewer鈥檚 introductory remarks and then decide whether to continue. One study made telephone calls to randomly selected households to ask opinions about the next election. In some calls, the interviewer gave her name; in others, she identified the university she was representing; and in still others, she identified both herself and the university. For each type of call, the interviewer either did or did not offer to send a copy of the final survey results to the person interviewed.

a. List the factors in this experiment and state how many levels each factor has.

b. If the researchers used every possible combination to form the treatments, how many treatments were included in the experiment?

c. List two of the treatments.

Eating on campus The director of student life at a small college wants to know what
