You are conducting a study to test whether there is a difference in the mean number of alcoholic drinks consumed per evening between the following groups: freshmen who live on campus (sample 1) and freshmen who live off campus (sample 2). Your results will be presented to the Dean of Students so that safety tips and prevention measures can be implemented for the appropriate groups. For freshmen who live on campus (N = 25), their mean number of drinks is 6.2, and their standard deviation is 2. For freshmen who live off campus (N = 30), their mean number of drinks is 3.8, and their standard deviation is 1.
