Since an instant replay system for tennis was introduced at a major​ tournament, men challenged

1428referee​ calls, with the result that 431of the calls were overturned. Women challenged 741referee​ calls, and 221 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Complete parts​ (a) through​ (c) below.

 Identify the test statistic.

Identify the​ P-value.

What is the conclusion based on the hypothesis​ test?

The​ P-value is greater than /less than the significance level of alphaequals0.05, so reject /fail to reject the null hypothesis. There is sufficient /is not sufficient evidence to warrant rejection of the claim that women and men have equal success in challenging calls.

Test the claim by constructing an appropriate confidence interval.

The 95% confidence interval is :

What is the conclusion based on the confidence​ interval?

Because the confidence interval limits include /do not include 0, there does not /does appear to be a significant difference between the two proportions. There is sufficient /is not sufficient evidence to warrant rejection of the claim that men and women have equal success in challenging calls.

Based on the​ results, does it appear that men and women may have equal success in challenging​ calls?

A.

The confidence interval suggests that there is no significant difference.

B.

The confidence interval suggests that there is a significant difference. It is reasonable to speculate that women have more success.

C.

The confidence interval suggests that there is a significant difference . It is reasonable to speculate that men have more success.

D.

There is not enough information to reach a conclusion.
