According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), 41% of college students nationwide engage in “binge drinking” behaviour, having five or more drinks in one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at the 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.
With a P-value > 0.10, which of the following conclusions is reasonable?
