Question
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1386 referee calls, with the result that 421 of the calls were overturned.
Women challenged 745 referee calls, and 222 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 (e) below.

Transcribed Image Text:What is the conclusion based on the hypothesis test?
The P-value is
the significance level of a = 0.05, so
women and men have equal success in challenging calls.
b. Test the claim by constructing an appropriate confidence interval.
The 95% confidence interval is < (P₁-P₂) <.
(Round to three decimal places as needed.)
What is the conclusion based on the confidence interval?
the null hypothesis. There
Because the confidence interval limits
0, there
evidence to warrant rejection of the claim that men and women have equal success in challenging calls.
evidence to warrant rejection of the claim that
appear to be a significant difference between the two proportions. There

Transcribed Image Text: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?
