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?
