Let

n1=80,

X1=60,

n2=80,

and

X2=70.

Complete parts (a) and (b) below.

a. At the

0.01

level of significance, is there evidence of a significant difference between the two population proportions?

Determine the null and alternative hypotheses. Choose the correct answer below.

H0: π1≥π2

H1: π1<>

H0: π1≤π2

H1: π1>π2

H0: π1=π2
