According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), and the National Institutes of Health (NIH), 41% of college students nationwide engage in "binge drinking" behavior, having 5 or more drinks in one occasion during the past two weeks. A 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 enrolled at the college. Of these, 132 admitted to having engaged in binge drinking. Based on the results of the test, a 95% confidence interval for the proportion of all students at this college that engage in binge drinking is O 0.338 to 0.423 O 0.343 to 0.418 O 0.328 to 0.430 0.341 to 0.420
