Question

A physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse Two sample T for Men vs Women of women. She randomly selected 55 men and 79 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 Mean 112.2 118.4 StDev 11.8 14.6 SE Mean 1.6 1.6 79 99% CI for mu Men-mu women -12.24, -0.16) T-Test mu Men mu Women (vs) T -2.71 P. 0.0038 DF. 128 (b) Identify the P-value and state the researcher's conclusion if the level of significance was ? = 0.01. What is the P-value? P-value .0038 State the researcher's conclusion. Which of the following is correct? A. Reject Ho, there is sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of women ( B. Fail to 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. 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 ( 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 Roun d to two decimal place s as needed.)

Explanation / Answer

b)here frm givne output p value =0.0038

for p value is less than 0.01 level ;

reject Ho; there is suffciient evidence to conclude ..........

c) lower bound =-12.24

upper bound =-0.16
