Two different simple random samples are drawn from two different populations. The first sample consists of 20 people with 11 having a common attribute. The second sample consists of 2000 people with 1443 of them having the same common attribute. Compare the results from a hypothesis test of p 1=p2 (with a 0.01 significance level) and a 99% confidence interval estimate of p 1 -p 2.

What are the null and alternative hypotheses for the hypothesis test?

A.

Upper H 0: p 1less than or equalsp 2

Upper H 1: p 1not equalsp 2

B.

Upper H 0: p 1greater than or equalsp 2

Upper H 1: p 1not equalsp 2

C.

Upper H 0: p 1equalsp 2

Upper H 1: p 1less thanp 2

D.

Upper H 0: p 1equalsp 2

Upper H 1: p 1not equalsp 2

E.

Upper H 0: p 1equalsp 2

Upper H 1: p 1greater thanp 2

F.

Upper H 0: p 1not equalsp 2

Upper H 1: p 1equalsp 2
