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): 0, 3, 4, 2, 1, 3, 2, 2, 2, 3
Males (Population 2): 7, 6, 5, 6, 5, 6, 8, 8, 8, 5
Give a 96.1% confidence interval for the difference between mean female and male
drink consumption. (Assume that the population variances are equal.)
