Since an instant replay system for tennis was introduced at a major tournament, men challenged 1410 referee calls, with the result that 424 of the calls were overturned. Women challenged 764 referee calls, and 223 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 hypothesis test? Identify the test statistic? Identify the P-value? What is the conclusion based on the hypothesis test? Is there enough evidence? b. Test the claim by constructing an appropriate confidence interval. The 99% confidence interval is ?

Question
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1410 referee calls, with the result that 424 of the calls were overturned. Women challenged 764 referee calls, and 223 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 hypothesis test?
Identify the test statistic?
Identify the P-value?
What is the conclusion based on the hypothesis test? Is there enough evidence?
b. Test the claim by constructing an appropriate confidence interval.
The
99% confidence interval is ? <p1−p2< ?.
What is the conclusion based on the confidence interval?
c. Based on the results, does it appear that men and women may have equal success in challenging calls?
