Please help.
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1408 referee calls, with the result that 419 of the calls were overturned. Women challenged 772 referee calls, and 217 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.
The P-value is
V the significance level of a =0.01 , so
V the null hypothesis. There
V 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) <
(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
V 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.
O 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.
