Since an instant replay system for tennis was introduced at a major tournament, men challenged 1401 referee calls, with the result that 413 of the calls were overturned. Women challenged 743 referee calls, and 217 of the calls were overtumed. Use a0.06 significance level to test the daim that men and
women have equal success in challenging calls. Complete parts (a) through (c) below.
