Conduct a test at the a = 0.10 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 21 > P2. The sample data are x1 = 127, ny = 241, X2 = 131, and n2 = 318. (a) Choose the correct null and alternative hypotheses below. O A. Ho: P1 = P2 versus Hy:...
