Since an instant replay system for tennis was introduced at a major tournament, men challenged 1387 referee calls, with the result that 420 of the calls were overturned. Women challenged 748 referee calls, and 210 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. 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? B. Ho: P1 = P2 O A. Ho: P1 = P2 H1: P1 P2 H1: P1 #P2 D. Ho: P1 #P2 H1: P1 = P2 O E. Ho: P1 S P2 H1: P1 #P2 F. Ho: P1 2 P2 H1: P1 # P2 Identify the test statistic. z=| (Round to two decimal places as needed.)

Question
please help solve attached image and below questions regarding attached image
identify the test statistic
identify the p value
what is the conclusion? the p value is greater than or less than the significance level of a=0.05 so we reject or fail to reject. there is not sufficent or sufficent evidence to warrant rejection of the claim that women and men have equal sucesses in challenging calls?
b) Test the claim by constructing an appropriate confidence interval. The 95% confidence interval is ___<(p1−p2) < ____.
c)
there does not or does appear to be a significant difference between the two proportions. There is sufficent or insufficent evidence to warrant rejection of the claim that men and women have equal success in challenging calls.
What is the conclusion based on the confidence interval? Because the confidence interval limits do include or do not include 0,
