dos cuarto

In a recent tennis tournament, women playing singles matches used challenges on 135 calls made by the line judges. Among those challenges, 38 were found to be successful with the call overturned. a. Construct a 99% confidence interval for the percentage of successful challenges. b. Compare the results from part (a) to this 99% confidence interval for the percentage of successful challenges made by the men playing singles matches: 23.2% < p <43.8%. Does it appear that either gender is more successful than the other? a. Construct a 99% confidence interval. % <p <% (Round to one decimal place as needed.) b. Choose the correct answer below. A. No conclusion can be made because not enough information is given about the confidence interval for men. B. The lower confidence limit of the interval for women is higher than the lower confidence limit of the interval for men and the upper confidence limit of the interval for women is also higher than the upper confidence limit of the interval for men. Therefore, women appear to be substantially more successful in their challenges. C. Since the upper confidence limit of the interval for men is higher than both the lower and upper confidence limits of the interval for women, this indicates that men appear to be substantially more successful in their challenges. D. Since the two confidence intervals overlap, neither gender appears to be substantially more successful in their challenges. E. The lower confidence limit of the interval for men is higher than the lower confidence limit of the interval for women and the upper confidence limit of the interval for men is also higher than the upper confidence limit of the interval for women. Therefore, men appear to be substantially more successful in their challenges. O F. Since the upper confidence limit of the interval for women is higher than both the lower and upper confidence limits of the interval for men, this indicates that women appear to be substantially more successful in their challenges.
