Since an instant replay system for tennis was introduced at a major
tournament, men challenged 1421 referee calls, with the result that
414 of the calls were overturned. Women challenged 758 referee
calls, and 217 of the calls were overturned. Use a 0.01

success in challenging calls. Identify the test statistic and the
p-value. Test the claim by constructing an appropriate confidence
interval. (99%)
