Since an instant replay system for tennis was introduced at a major tournament, men challenged 1383 referee calls, with the result that 427 of the calls were overturned. Women challenged 778 referee calls, and 230 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Complete parts (a) through (c) below. 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? OC. Ho: P1 P2 O B. Ho: P1=P2 OA. Ho: P₁ = P2 H₁: P₁ P2 H₁: P₁ P2 H₁: P₁ P2 OE. Ho: P₁ OD. Ho: P₁ SP2 P2 P2 OF. Ho: P1 P2 H₁: P₁ P₂ H₁: P₁ H₁: P₁ P₂ dentify the test statistic. (Round to two decimal places as needed.) dentify the P-value. P-value= (Round to three decimal places as needed.)
