a. Test the claim using a hypothesis test.

(Round to three decimal places as needed.)
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) <

What is the conclusion based on the confidence interval?
the null hypothesis. There

appear to be a significant difference between the two proportions. There
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?
