Since an instant replay system for tennis was introduced at a major tournament, men challenged 1429 referee calls, with the result that 416 of the calls were overturned. Women challenged 762 referee calls, and 224 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. 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 B. Ho: P1 =P2 H: P1 > P2 O C. Ho: P1 = P2 O A. Ho: P1 =P2 H1: P1 + P2 H1: P1

Since an instant replay system for tennis was introduced at a major​ tournament, men challenged 1429 referee​ calls, with the result that 416 of the calls were overturned. Women challenged 762 referee​ calls, and 224 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.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1429 referee calls, with the result that 416 of the calls were
overturned. Women challenged 762 referee calls, and 224 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.
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 B. Ho: P1 = P2
H1: P1 > P2
OC. Ho: P1 = P2
O A. Ho: P1 = P2
H1: P1 + P2
H1: P1 <P2
O F. Ho: P1 2 P2
O D. Ho: P1 + P2
H1:P1 = P2
O E. Ho: P1 SP2
H1: P1 # P2
H1: P1 # P2
Identify 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 is
V the significance level of a = 0.05, so
V the null hypothesis. There
evidence to warrant rejection of the claim
that women and men have equal success in challenging calls.

b. Based on the results, does it appear that men and women have equal success in challenging calls?
O A. It appears that men and women have equal success in challenging calls.
O B. It does not appear that men and women have equal success in challenging calls. Women have more success.
O C. It does not appear that men and women have equal success in challenging calls. Men have more success.
O D. The results are inconclusive.
