Please help. I am getting the rejection region wrong

(1 point) Independent random samples, each containing 600 observations, were selected from two binomial populations. The samples from populations 1 and 2 produced 375 and 369 successes, respectively. (a) Test Ho : (p1 - p2) = 0 against Ha : (p1 - p2) # 0. Use a = 0.07 test statistic = 0.3568 rejection region | z| > 1.81 The final conclustion is OA. There is not sufficient evidence to reject the null hypothesis that (p1 - p2) = 0. OB. 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 = 0.05 test statistic = 0.3568 rejection region z > 2.0 The final conclustion is O A. There is not sufficient evidence to reject the null hypothesis that (p1 - p2) = 0. OB. We can reject the null hypothesis that (p1 - p2) = 0 and accept that (P1 - P2) > 0
