A sample of 65 observations is selected from one population. The sample mean is 2.67 and the
sample standard deviation is 0.75. A sample of 50 observations is selected from a second population.

test of hypothesis using the .08 significance level.
H0: u1<=u2
H1: u1 > u2
a. Is this a one-tailed or a two-tailed test?
b. State the decision rule.
c. Compute the value of the test statistic.
d. What is your decision regarding H0?
e. What is the p-value?
