Since an instant replay system for tennis was introduced at a majortournament, men challenged 1434 refereecalls, with the result that 424 of the calls were overturned. Women challenged 768 refereecalls, and 211 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?
Identify the test statistic.
Identify theP-value.
What is the conclusion based on the hypothesistest?
b. Test the claim by constructing an appropriate confidence interval.
The 99% confidence interval is ______<(p1p2)<_______.
c. Based on theresults, does it appear that men and women may have equal success in challengingcalls?
a)The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that men have more success.
b)The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.
This is the correct answer.
c)The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that women have more success.
Your answer is not correct.
d)There is not enough information to reach a conclusion.
