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 H_a: 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 z_scores for the test, state your decision rule, and report your decision.
