Question: Student drinking. The College Alcohol Study interviewed a sample of 14,941 college students about their drinking habits. The overall effect of the sample design is close to an SRS of students. The response rate was more than 60%. This is quite good for a national sample though nonresponse is as usual the biggest weakness of this survey. Of the students in the sample, 10,010 supported cracking down on underage drinking. Estimate with 99% confidence the proportion of all college students who feel this way.
