Question

Since an instant replay system for tennis was introduced at a major​ tournament, men challenged 1437 referee​ calls, with the result that 420 of the calls were overturned. Women challenged 762 referee​ calls, and 225 of the calls were overturned. Use a 0.01 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?

A. Upper H 0​: p 1equalsp 2 Upper H 1​: p 1less thanp 2

B. Upper H 0​: p 1greater than or equalsp 2 Upper H 1​: p 1not equalsp 2

C. Upper H 0​: p 1equalsp 2 Upper H 1​: p 1not equalsp 2

D. Upper H 0​: p 1less than or equalsp 2 Upper H 1​: p 1not equalsp 2

E. Upper H 0​: p 1equalsp 2 Upper H 1​: p 1greater thanp 2

F. Upper H 0​: p 1not equalsp 2 Upper

H 1​: p 1equalsp 2 Identify the test statistic. zequals nothing ​(Round to two decimal places as​ needed.)

Identify the​ P-value. ​P-valueequals nothing ​(Round to three decimal places as​ needed.)

What is the conclusion based on the hypothesis​ test?

The​ P-value is ▼ greater than less than the significance level of alphaequals 0.01​, so ▼ fail to reject reject the null hypothesis. There ▼ is sufficient is not sufficient evidence to warrant rejection of the claim that women and men have equal success in challenging calls.

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

The 99​% confidence interval is nothing less than left parenthesis p 1 minus p 2 right parenthesis less than nothing.
