Conduct a test at the α=0.01 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 p1>p2. The sample data are x1=129​, n1=241​, x2=139​, and n2=312. ​(a) Choose the correct null and alternative hypotheses below.     A. H0: p1=p2 versus H1: p1≠p2   B. H0: p1=p2 versus H1: p1>p2 Your answer is correct.   C. H0: p1=p2 versus H1: p1
