In each of Exercises, we have stated the purpose for performing a hypothesis test to compare the means, µ1 and µ2, of two populations. For each exercise,

a.determine the null and alternative hypotheses. Note: Always place the mean of Population 1 on the left.

b.classify the hypothesis test as two tailed, left tailed, or right tailed.

The primary concern is deciding whether the mean of Population 2 differs from the mean of Population 1.
