    The null and alternate hypotheses are:
    H0: u1 equal 2
    H1: u1 not equal to 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?

    Note: Use the five-step hypothesis testing procedure for the following exercises.
