Question
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1421 referee calls, with the result that 418 of the calls were
overturned. Women challenged 778 referee calls, and 228 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.
O A. Ho: P1 = P2
O C. Ho:P1 = P2
H1: P1 > P2
O B. Ho:P1 = P2
H1: P1 #P2
H1: P1 <P2
O D. Ho: P1 2P2
H1: P1 #P2
O E. Ho: P1 SP2
H1: P1 #P2
O F. Ho: P1 #P2
H1: P1 = P2
Identify the test statistic.
(Round to two decimal places as needed.)
Identify the P-value.
P-value =
(Round to three decimal places as needed.)

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1421 referee calls, with the result that 418 of the calls were
overturned. Women challenged 778 referee calls, and 228 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.
The P-value is greater than the significance level of a = 0.01, so fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim
that women and men have equal success in challenging calls.
b. Test the claim by constructing an appropriate confidence interval.
The 99% confidence interval is< (P1 - P2) <U.
(Round to three decimal places as needed.)
What is the conclusion based on the confidence interval?
Because the confidence interval limits
V 0. there
V 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?
