(2 points) Independent random samples, each containing 600 observations, were selected from
two binomial populations. The samples from populations 1 and 2 produced 451 and 229
successes, respectively. (a) Test H0:(p1p2)=0 against Ha:(p1p2)=0. Use =0.01 test statistic =
rejection region z> The final conclustion is A. There is not sufficient evidence to reject the null
hypothesis that (p1p2)=0. B. We can reject the null hypothesis that (p1p2)=0 and accept that
(p1p2)=0. (b) Test H0:(p1p2)=0 against Ha:(p1p2)>0. Use =0.09 test statistic = rejection region
z> The final conclustion is A. We can reject the null hypothesis that (p1p2)=0 and accept that
(p1p2)>0. B. There is not sufficient evidence to reject the null hypothesis that (p1p2)=0.
