Statistics 10

Conduct a test at the a = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether P, > P2. The sample data are x1 = 122, n, = 255, X2 = 141, and n2 = 313. (a) Choose the correct null and alternative hypotheses below. O A. Ho: P1 = P2 versus H1 : P1 P2 O D. Ho: P1 = 0 versus H1 : P, # 0 (b) Determine the test statistic. Zo = (Round to two decimal places as needed.)
