Since an instant replay system for tennis was introduced at a major tournament, men challenged 1412 referee calls, with the result that 411 of the calls were overturned. Women challenged 764
referee calls, and 227 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. Complete parts (a) through (c) below.

The P-value is greater than the significance level of a=0.01, so fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that women and men have
equal success in challenging calls.
b. Test the claim by constructing an appropriate confidence interval
The 99% confidence interval is < (P₁-P₂)<
