Part 1

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?

H0:

p1=p2

H1:

p1≠p2

H0:

p1≤p2

H1:

p1≠p2

H0:

p1=p2

H1:

p1>p2

H0:

p1≥p2

H1:

p1≠p2

H0:

p1≠p2

H1:

p1=p2

H0:

p1=p2

H1:

p1<p2

(Round to three decimal places as needed.)

Part 4

What is the conclusion based on the hypothesis test?

The P-value is

evidence to warrant rejection of the claim that women and men have equal success in challenging calls.

Part 5

b. Test the claim by constructing an appropriate confidence interval.

The

99%

confidence interval is

(Round to three decimal places as needed.)

Part 6

What is the conclusion based on the confidence interval?

Because the confidence interval limits

evidence to warrant rejection of the claim that men and women have equal success in challenging calls.

Part 7

c. Based on the results, does it appear that men and women may have equal success in challenging calls?

The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that men have more success.

The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that women have more success.

The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.

There is not enough information to reach a conclusion.
