Binge drinking is defined by the u. s. department of health and human services as the consumption of 5 or more drinks in a row for men and 4 or more for women. in a recent study of 400 college students, 181 of them reported to have engaged in binge drinking in the past two weeks. the report concluded that half of all college students binge drink. test this claim at the 0.10 significance level. construct a 95% confidence interval for the proportion of college students who binge drink (hint: you will need to look back at chapter 7 to answer this question).
(a) what is the critical value for z for this confidence interval?
(b) calculate the margin of error?
(c) determine the confidence interval?
