Random samples of female and male UVA undergraduates are asked to estimate the number of alcoholic drinks that each consumes on a typical weekend. The data is below: Females (Population 1): 4, 3, 3, 5, 4, 3, 4, 2, 6, 5

Males (Population 2): 5, 8, 5, 8, 9, 6, 5, 7, 8, 5

Give a 95% confidence interval for the difference between mean female and male drink consumption. (Assume that the population variances are equal.)
