Question 8 According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), 41% of college students nationwide engage in "binge drinking" behavior, having five or more drinks in one occasion during the past two weeks. A Not yet college president wonders if the proportion of students enrolled at her college that binge drink is actually lower than the national proportion. In a commissioned study, 348 students are selected randomly from a list of all students answered enrolled at the college. Of these, 132 admitted to having engaged in binge drinking. Marked out of 1.0 Reference: Ref 18-4 Flag question With a P-value between 0.10 and 0.15, which of the following conclusions is reasonable? Select one: O a. We can't reach any reasonable conclusion because the assumptions necessary for a significance test for a proportion are not met in this case. O b. There is little evidence to support a conclusion that the proportion of students at this particular college that binge drink is lower than the national proportion of 0.41. O c. There is strong evidence that the proportion of students at this college that binge drink is lower than the national proportion of 0.41. O d. There is moderate but not strong evidence that the proportion of binge drinking students at this college is lower than the national proportion of 0.41. Question 9 In 1965, about 44% of the U.S. adult population had never smoked cigarettes. A national health survey of 1205 U.S. adults (presumably selected randomly) during 2006 revealed that 615 had never smoked cigarettes. Not yet Reference: Ref 18-5 answered Marked out of 1.0 Suppose you wished to test whether there has been a change since 1965 in the proportion of U.S. adults that have never smoked cigarettes. Which of the following are the appropriate hypotheses? Flag question Select one: O a. Ho: P = 0.44, Ha: P > 0.44 O b. Ho: P = 0.44, Ha: P
