Question 12 10 pts For two populations, the proportion of population A is hypothesized to be not different from the proportion in population B. A sample of i 200 from population A resulted in 170 "successes, while a sample of 150 from population B resulted in 110 "successes Test the hypothesis with a significance level of .05. (See pages 474ff in the textbook) O The critical value of rist-1.96 1.96); the pooled proportion-8, the 2-statistic is 2.7: the decision is to reject the nult, the meaning is that the proportions in the two populations are probably not equal The critical value of "r" is (-1.645, 1.645); the pooled proportion-0432; the z-statistic is 1.28: the decision is do not reject the null; the meaning is that the proportions in the two populations are probably equal The critical value of "ris (-2.576, 2.576); the pooled proportion-75; the 2-statistic is 11167: the decision is to fail to reject the null; the meaning is that the proportions in the two populations are most likely equal O The critical value of "r" is (-1.28, 1.28); the pooled proportion-1167; the 2-statistic is (-1.645); the decision is to reject the null; the meaning is that the proportions in the two populations are probably equal
