You have a random sample of 100 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: p1 .42 and p2 .38. Compute p pooled.
b. Calculate the sample test statistic, z stat.
c. Using a significance level of .10, determine the critical zscores for the test, state your decision rule, and report your decision.
