Question 1:

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1391 referee calls, with the result that 424 of the calls were overturned. Women challenged 747 referee calls, and 222 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. 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? O A. HO: P1 SP2 OB. HO: P1 2 P2 O C. Ho: P1 = P2 H1: P1 # P2 H1 : P1 # P2 H1 : P1 > P2 O D. Ho: P1 = P2 OE. HO: P1 = P2 OF. HO: P1 # P2 H1 : P1
