Since an instant replay system for tennis was introduced at amajor​ tournament, men challenged 1427 referee​ calls, with theresult that 411 of the calls were overturned. Women challenged 747referee​ calls, and 215 of the calls were overturned. Use a 0.01significance level to test the claim that men and women have equalsuccess in challenging calls. Complete parts​ (a) through​ (c)below. a. Test the claim using a hypothesis test. Consider thefirst sample to be the sample of male tennis players who challengedreferee calls and the second sample to be the sample of femaletennis players who challenged referee calls. What are the null andalternative hypotheses for the hypothesis​ test?

Identify the test statistic.

z=?

​(Round to two decimal places as​ needed.)

Identify the​ P-value.

​P-value=?

​(Round to three decimal places as​ needed.)

What is the conclusion based on the hypothesis​ test?

The​ P-value is greater than or less than ?

the significance level of alpha equals 0.01​, so

reject or fail to reject ? the nullhypothesis.

There is sufficient or is not sufficient ?

evidence to warrant rejection of the claim that women and menhave equal success in challenging calls.

b. Test the claim by constructing anappropriate confidence interval.

The 99% confidence interval is ?

? < (p 1 - p 2)< ?

.

​(Round to three decimal places as​ needed.)

What is the conclusion based on the confidence​ interval?

Because the confidence interval limits include or do notinclude? 0,

there does not or does ?

appear to be a significant difference between the twoproportions.

There is not sufficient or is sufficient?evidence to warrant rejection of the claim that men and women haveequal success in challenging calls.

c. Based on the​ results, does it appear thatmen and women may have equal success in challenging​ calls?

A. The confidence interval suggests that there is a significantdifference between the success of men and women in challengingcalls. It is reasonable to speculate that men have moresuccess.

B. The confidence interval suggests that there is no significantdifference between the success of men and women in challengingcalls.

C. The confidence interval suggests that there is a significantdifference between the success of men and women in challengingcalls. It is reasonable to speculate that women have moresuccess.

D. There is not enough information to reach a conclusion.
