In 2006, use of the Hawk-Eye computer system was initiated at U.S. Open tennis matches. Players could challenge chair umpire and line judge calls, and the Hawk-Eye system was used to decide whether the call was correct or wrong. The table below shows results of player challenges in men’s and women’s singles games in which the Hawk-Eye system was used. The data are current at the time of this writing. Use a 0.05 significance level to test the claim that the gender of the tennis player is independent of whether the call is overturned. Do players of either gender appear to be better at challenging calls?
