Date: 03/02/20 7. Since an instant replay system for tennis was introduced at a major toumament, men challenged 1412 referee calls, with the result that 422 of the calls were overturned. Women challenged 740 referee calls and 222 of the calls were owemumed. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Complete paris (a) through (c) below. a. Tost the claim using a hypothesis test. hypotheses for the 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 is the conclusion based on the hypothesis test? _the hypothesis. There (3) – evidence to warrant rejection of the claim that women and men have equal success in The P-value is (1) the significance level of 0.05, so (2)_ challenging calls b. Test the claim by constructing an appropriate confidence interval. The 95% confidence interval is (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? Because the confidence interval limits (4) men and women have equal success in challenging calls. 0, there (5) appear to be a significant difference between the two proportions. There (6) evidence to warrant rejection of the claim that Radon the rated 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 a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that men have more success. OB. 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 OC. The confidence interval suppests that there is no significant difference between the success of men and women in challenging calls O D.
