Question
A physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She
randomly selected 59 men and 73 women to participate in the study. Each subject was required to step up and down a 6-inch
platform. The pulse of each subject was then recorded. The following results were obtained.

State the researcher's condlusion. Which of the following is correct?
O A Reject Ha, there is sufficient evidence to condlude that the mean step pulse of men was less than the mean step pulse of women
the mean step pulse of women
O B. Reject Ha, there is not sufficient evidence to condlude that the mean step pulse of men was less
OC. Fail to reject Ho, there is sufficient evidence to conclude that the mean step pulse of men was less than the mean steg pulse of women
O D. Fail to reject Ho, there is not sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of women
(c) What is the 99% confidence interval for the mean difference in pulse rates of men versus women?
The lower bound is
The upper bound is
(Round to two decimal places as needed.)
Interpret this result
O A. We are 99% confident that the mean difference is in the confidence interval.
O B. 99% percent of the time the mean difference is in the confidence interval.
OC. 99% percent of the time the means are in the confidence interval.
O D. We are 99% confident that the means are in the confidence interval.
