Question 1
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.
