Independent random samples, each containing 600 observations, were selected from two binomial populations. The samples from populations 1 and 2 produced 277 and 338 successes, respectively. (a) Test H0:(p1−p2)=0 against Ha:(p1−p2)≠0. Use α=0.01
test statistic =
(b) Test H0:(p1−p2)=0 against Ha:(p1−p2)>0. Use α=0.08
test statistic =
