Independent random samples, each containing 60 observations, were selected from two populations. The samples from populations 1 and 2 produced 26 and 15 successes, respectively. Test H0:(p1−p2)=0 against Ha:(p1−p2)>0 Use α=0.08

(a) The test statistic is

(b) The P-value is

(c) The final conclusion is

A. We can reject the null hypothesis that (p1−p2)=0 and accept that (p1−p2)>0

B. There is not sufficient evidence to reject the null hypothesis that (p1−p2)=0
