In a recent tennis tournament, women playing singles matches used challenges on 134 calls made by the line judges. Among those challenges, 33 were found to be successful with the call overturned. a) Construct a 95% confidence interval for the percentage of successful challenges. b) Compare the results from part (a) to this 95% confidence interval for the percentage of successful challenges made by the men playing singles matches: 19.8 % < p < 35.1 %. Does it appear that either gender is more successful than the other?
