Independent random samples, each containing 90 observations, were selected from two populations. The samples from populations 1 and 2 produced 73 and 64 successes, respectively.
Test H0:(p1−p2)=0 against Ha:(p1−p2)≠0. Use α=0.09

The P-value is

The final conclusion is

A. There is not sufficient evidence to reject the null hypothesis that (p1−p2)=0
B. We can reject the null hypothesis that (p1−p2)=0 and accept that (p1−p2)≠0
