Since an instant replay system for tennis was introduced at a major tournament, men challenged 1433 referee calls, with the result that 411 of the calls were overturned. Women challenged 750 referee calls, and 211 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.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

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

Transcribed Image Text:P-value =|
(Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
v the null hypothesis. There
V the significance level of a = 0.01, so
claim that women and men have equal success in challenging calls.
The P-value is
evidence to warrant rejection of the
b. Test the claim by constructing an appropriate confidence interval.
The 99% confidence interval is < (P1 - P2) <U

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?
O B. Ho: P1 # P2
O A. Ho: P12 P2
H1: P1 #P2
O C. Ho P1 = P2
H: P1> P2
H: P1 P2
O E. Ho: P1 = P2
O D. Ho: P1 = P2
H1: P1 P2
O F. Ho: P1 SP2
H, P1 P2
H1: P1 <P2
Identify the test statistic.
