    The null and alternate hypotheses are:

    H0: mean of 1 is equal to the mean of 2
    H2: mean of 1 is not equal to the mean of 2

    A random sample of 15 observations from the first population revealed a sample mean of 350 and a sample standard deviation of 12. A random sample of 17 observations from the second population revealed a sample mean of 342 and a sample standard deviation of 15.

    At the .10 significance level, is there a difference in the population means?
