IV.17. Do you drink? In a July 2014 Gallup Poll a random sample of 1013 adults were asked whether they drank alcoholic beverages (liquor, wine, or beer) or completely abstained from drinking any alcohol. Among respondents, 365 said that they completely abstain from drinking alcohol. Assume that the sample was an SRS. Is this good evidence that more than one-third of American adults completely abstain from drinking alcoholic beverages? Show the five steps of the test (hypotheses, sampling distribution, data, P-value, conclusion) clearly. Use a significance level of 0.05. (Hint: See pages 522–531.)

The following exercises are based on the optional material in Chapters 21, 22, and 24.
