Question

Conduct the following test at the ? = 0.01 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume that the samples were obtained independently using simple random sampling. Test whether p1 ? p2. Sample data are x1 = 28, n1 = 254, x2 = 36, and n2 = 302. (a) Determine the null and alternative hypotheses. Choose the correct answer below: A. H0: p1 = p2 versus H1: p1 ? p2 B. H0: p1 = p2 versus H1: p1 < p2 C. H0: p1 = 0 versus H1: p1 ? 0 D. H0: p1 = p2 versus H1: p1 > p2 (b) The test statistic z0 is ___. (Round to two decimal places as needed.)
