# Question: You have a random sample of 500 population members from

You have a random sample of 500 population members from each of two populations and you want to set up a test for the following hypotheses: H0: μ1 – μ2 < 0 Ha: μ1 – μ2 > 0

a. Suppose the sample results are: 1 = .31 and 2 = .25. Compute pooled.

b. Calculate the sample statistic, z stat.

c. Using a significance level of .05, determine the critical zscore for the test, state your decision rule and report your decision.
