Question:

Independent random samples of n1 = 233 and n2 = 312 are selected from two populations and used to test the hypothesis H0: (µ1 - µ2) = 0 against the alternative Ha: (µ1 - µ2) ≠ 0.
a. The two-tailed p-value of the test is .1150. Interpret this result.
b. If the alternative hypothesis had been Ha: (µ1 - µ2) < 0, how would the p-value change? Interpret the p-value for this one-tailed test.
