Women challenged 769 refereecalls, and 220 of the calls were overturned. Use a 0.01 significance level to test the claim that men and women have equal success in challenging calls. Complete parts(a) through(c) below.
a. Test the claim using a hypothesis test.
Consider the first sample to be the sample of male tennis players who challenged referee calls and the second sample to be the sample of female tennis players who challenged referee calls. What are the null and alternative hypotheses for the hypothesistest?

H1: p1p2
C.
H0: p1p2
H1: p1=p2
D.
H0: p1=p2
H1: p1 E. H0: p1=p2 H1: p1p2 F. H0: p1=p2 H1: p1> b. Test the claim by constructing an appropriate confidence interval. c. c. Based on theresults, does it appear that men and women may have equal success in challengingcalls?
