Question

Since an instant replay system for tennis was introduced at a major​ tournament, men challenged

1407
 

referee​ calls, with the result that

425
 

of the calls were overturned. Women challenged

771
 

referee​ calls, and

213
 

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 1

equalsp 2

Upper H 1
​:
p 1

not equalsp 2

 
 
B.
Upper H 0
​:
p 1

not equalsp 2

Upper H 1
​:
p 1

equalsp 2

 
 
C.
Upper H 0
​:
p 1

greater than or equalsp 2

Upper H 1
​:
p 1

not equalsp 2

 
 
D.
Upper H 0
​:
p 1

equalsp 2

Upper H 1
​:
p 1

less thanp 2

 
 
E.
Upper H 0
​:
p 1

less than or equalsp 2

Upper H 1
​:
p 1

not equalsp 2

 
 
F.
Upper H 0
​:
p 1

equalsp 2

Upper H 1
​:
p 1

greater thanp 2

​(Round to three decimal places as​ needed.)
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.
c. Based on the​ results, does it appear that men and women may have equal success in challenging​ calls?
 
 
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 speculate that women have more success.
 
B.
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.
 
C.
The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.
 
D.
There is not enough information to reach a conclusion.
