Since an instant replay system for tennis was introduced at a major tournament, men challenged 1388 referee calls, with the result that 429 of the calls were overturned.Women challenged 769 referee calls, and 212 of the calls were overturned. Use a 0.01 significance level to test the claim that men and women have equal success inchallenging 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 whochallenged referee calls. What are the null and alternative hypotheses for the hypothesis test?OA. Ho: P₁ P2OB. Ho: P₁ P2H₁: P₁ = P₂OC. Ho: P₁ ≤P2H₁: P₁ P₂H₁: P₁P₂O D. Ho: P₁ = P₂E. Ho: P₁ = P2H₁: P₁ P2OF. Ho: P₁ = P₂H₁: P₁ P2H₁: P₁ P₂Identify the test statistic.Z=(Round to two decimal places as needed.)Identify the P-value.P-value =(Round to three decimal places as needed.)What is the conclusion based on the hypothesis test?The P-value isthe null hypothesis. Thereevidence to warrant rejection of the claimthe significance level of α = 0.01, sothat women and men have equal success in challenging calls.b. Test the claim by constructing an appropriate confidence interval.The 99% confidence interval is < (P₁-P₂) <.(Round to three decimal places as needed.)What is the conclusion based on the confidence interval?▼0, thereappear to be a significant difference between the two proportions. ThereBecause the confidence interval limitsevidence to warrant rejection of the claim that men and women have equal success in challenging calls.c. Based on the results, does it appear that men and women may have equal success in challenging calls?O A. The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculatethat men have more success.O B. The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.O C. The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculatethat women have more success.O D. There is not enough information to reach a conclusion.
