Since an instant replay system for tennis was introduced at a major tournament, men challenged 1421 referee calls, with the result that 422 of the calls were overturned. Women challenged 747 referee calls, and 213 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. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is (greater than/less than/equal to) the significance level of a=0.01, 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. (round to three decimal places as needed) What is the conclusion based on the confidence interval? Because the confidence interval limits (do not include/include) 0, there (does/does not) appear to be a significant difference between the two proportions. There (is not sufficient/is sufficient) evidence to warrant rejection of the claim that mean and women have equal success in challenging calls. The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.

Question
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1421 referee calls, with the result that 422 of the calls were overturned. Women challenged 747 referee calls, and 213 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.
(Round to two decimal places as needed.)
Identify the P-value.
(Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
The P-value is (greater than/less than/equal to) the significance level of a=0.01, 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.
(round to three decimal places as needed)
What is the conclusion based on the confidence interval?
Because the confidence interval limits (do not include/include) 0, there (does/does not) appear to be a significant difference between the two proportions. There (is not sufficient/is sufficient) evidence to warrant rejection of the claim that mean and women have equal success in challenging calls.
The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.
