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 (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 fo
the hypothesis test?
A. Ho: P₁ = P2
H₁: P₁ P2
D. Ho: P₁ P2
H₁: P₁ P₂
Identify the test statistic.
Z=
(Round to two decimal places as needed.)
Identify the P-value.
P-value =
(Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
The P-value is
the significance level of α = 0.05, so
b. Test the claim by constructing an appropriate confidence interval.
The 95% confidence interval is < (P₁-P₂) <.
