Question

what is the conclusion based on the confidence interval?
because the confidence interval limits 0, there appear to be a significant difference between the two proportions. there is not sufficient 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 no significant difference between the success of men and women in challenging calls.
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 a significant difference between the success of men and women in challenging calls. it is reasonable to speculate that women have more success.
d. there is not enough information to reach a conclusion.

Explanation:

To determine the conclusion from the confidence interval, we analyze if 0 is within the interval (implies no significant difference) or not (implies a difference). If the interval includes 0, there's not enough evidence to reject the claim of equal success, so the confidence interval suggests no significant difference (matching option A's logic about no significant difference).

Answer:

A. The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.
