Question

Independent random samples, each containing 70 observations, were selected from two populations. The samples from populations 1 and 2 produced 33 and 23 successes, respectively. Test H 0 :( p 1 − p 2 )=0 H0:(p1−p2)=0 against H a :( p 1 − p 2 )≠0 Ha:(p1−p2)≠0 . Use α=0.01 α=0.01 . (a) The test statistic is

(b) The P-value is

(c) The final conclusion is

A. We can reject the null hypothesis that ( p 1 − p 2 )=0 (p1−p2)=0 and accept that ( p 1 − p 2 )≠0 (p1−p2)≠0 .

B. There is not sufficient evidence to reject the null hypothesis that ( p 1 − p 2 )=0 (p1−p2)=0 .
