Independent random samples, each containing 500 observations, were selected from two binomial populations. The samples from populations 1 and 2 produced 136 and 421 successes, respectively. (a) Test Ho : (P1 - P2) = 0 against Ha : (P1 - P2) # 0. Use a = 0.08 test statistic = rejection region |z| > The final conclustion is O A. There is not sufficient evidence to reject the null hypothesis that (P1 - P2) = 0. O B. We can reject the null hypothesis that (P1 - P2) = 0 and accept that (p1 - P2) # 0. (b) Test Ho : (P1 - P2) = 0 against Ha : (P1 - P2) > 0. Use a = 0.02 test statistic = rejection region z > The final conclustion is O A. We can reject the null hypothesis that (P1 - P2) = 0 and accept that (P1 - P2) > 0. O B. There is not sufficient evidence to reject the null hypothesis that (P1 - P2) = 0.
