Since an instant replay system for tennis was introduced at a major tournament, men challenged 1437 referee calls, with the result that 431 of the calls were overturned. Women challenged 778 referee calls, and 229 of the calls were overturned. Use a 0.01 significance level test the claim that men and women have equal success in challenging calls. Complete parts (a) through (c) below.

Question
b. Test the claim by constructing an appropriate confidence interval.
The 99% confidence interval is| < (P1 - P2) <
(Round to three decimal places as needed.)
What is the conclusion based on the confidence interval?
Because the confidence interval limits
0, there
appear to be a significant difference between the two proportions. There
evidence to warrant rejection of the claim that men and women
have equal success in challenging calls.
c. Based on the results, does it appear that men and women may have equal success in challenging calls?
O A. The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.
B. 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.
O 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.
O D. There is not enough information to reach a conclusion.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1437 referee calls, with the result that 431 of the calls were overturned. Women challenged 778 referee calls, and 229 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?
O A. Ho: P1 <p2
H1: P1 # P2
О В. Но: Р1 -Р2
H1: P1 # P2
O C. Ho: P1 = P2
H1: P1 > P2
D. Ho: P1 = P2
H1: P1 <P2
O E. Ho: P1 # P2
H1: P1 = P2
O F. Ho: P1 2 P2
H4: P, #P2
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
the significance level of a = 0.01, so
the null hypothesis. There
evidence to warrant rejection of the claim that women and men have equal success in challenging calls.
