Transcribed Image Text: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 53 men and 78 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.
Two sample T for Men vs Women

99% CI for mu Men - mu Women

T-Test mu Men = mu Women (vs <)

(b) Identify the P-value and state the researcher's conclusion if the level of significance was a = 0.01. What is the P-value?
P-value = 0.0042
State the researcher's conclusion. Which of the following is correct?
A. 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
B. Reject Ho, there is sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of women
C. 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
