=+how often they drank alcoholic beverages. For the sorority rush group, the mean was 2.72 drinks per week and the standard deviation .86. For the group who did not rush, the mean was 2.11 and the standard deviation 1.02. Is there evidence to support the claim that those who rush a sorority drink more than those who do not rush? Test the relevant hypotheses using a 5 .01. What assumptions are required in order for the two-sample t test to be appropriate?
