Question

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1434 referee calls, with the result that 423 of the calls were overturned. Women challenged 771 referee calls, and 210 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. Identify the test statistic, z= .Identify the P-value, P-value= .Test the claim by construction an appropriate confidence interval.

Answer #1

Null Hypothesis

Alternative Hypothesis

Under H0, the test statistic is

where

The test statistic is

Significance level

The P-Value is 0.26314

Since p value os greater than significance level, Fail to Reject H0.

Hence, at 1% significance level, we have enough evidence to conclude that men and women have equal success in challenging calls.
