Assume that you plan to use a significance level of α = 0.05 to test the claim that p₁ = P2. Use the given sample sizes and numbers of successes to find (a) the pooled estimate p, (b) the z test statistic, (c) the critical z values, and (d) the P-value. 6. Sample 1 n₁ = 50 x₁ = 25 Sample 2 n2 = 100 x2 = 55
