Since an instant replay system for tennis was introduced at a major tournament, men challenged 1384 referee calls, with the result that 428 of the calls were overturned. Women challenged 766 referee calls, and 219 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) a. Test the claim using a hypothesis test. Consider the first sample to be the sample of male tennis players who challenged referee calls and the second sample to be the sample of female tennis players who challenged referee calls. What are the null and alternative hypotheses for the hypothesis test? OA. Ho: P1 P2 H₁: P₁ P₂ O D. Ho: P1 = P2 H₁: P₁ P2 Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. O B. Ho: P₁ SP2 H₁: P₁ P2 OE. Ho: P1 H₁: P₁ C P2 P2 OC. Ho: P1 H₁: P₁ OF. Ho: P1 H₁: P₁ P2 P2 P2 P2
