Part 3

Identify the P-value.

P-value= ?

(Round to three decimal places as needed.)

Part 4

What is the conclusion based on the hypothesis test?

The P-value is

▼

greater than or

less than

the significance level of

α=0.05,

▼

fail to reject or

reject

the null hypothesis. There

▼

is not sufficient or

is sufficient

evidence to warrant rejection of the claim that women and men have equal success in challenging calls.

Part 5

b. Test the claim by constructing an appropriate confidence interval.

The

95%

confidence interval is

? (<p1−p2<) ?

(Round to three decimal places as needed.)

Part 6

What is the conclusion based on the confidence interval?

Because the confidence interval limits

▼

do not include or

include

0, there

▼

does not or

does

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

▼

is sufficient or

is not sufficient

evidence to warrant rejection of the claim that men and women have equal success in challenging calls.

Part 7

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

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.

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.

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

There is not enough information to reach a conclusion.
