Since an instant replay system for tennis was introduced at a major tournament, men challenged 1410 referee calls, with the result that 423 of the calls were overturned. Women challenged 751 referee calls, and 214 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.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
