Two sample I for Men vs Women physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She randomly selected 55 men d 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 corded. The following results were obtained. Mean StDev Men Women 90% Cl for mu Men (- 10.09, - 2.51) T-Test mu Men = mu Women (vs <) T= - 2.77 P = 0.0032 DF = 125 55 112.3 11.4 73 118.6 14.3 mu Women State the null and alternative hypotheses. Which of the following is correct? A. Ho: H1 = H2; Ha: H1 # H2 B. Ho: H1 = H2; Hạ: H1 > H2 C. Ho: H1 = H2; Hạ: H1

The following results were obtained. Mean StDev Men Women 90% Cl for mu Men (- 10.09, - 2.51) T-Test mu Men = mu Women (vs <) T= - 2.77 P = 0.0032 DF = 125 55 112.3 11.4 73 118.6 14.3 mu Women State the null and alternative hypotheses. Which of the following is correct? A. Ho: H1 = H2; Ha: H1 # H2 B. Ho: H1 = H2; Hạ: H1 > H2 C. Ho: H1 = H2; Hạ: H1 <H2 Identify the P-value and state the researcher's conclusion if the level of significance was a = 0.01. What is the P-value? value = ate 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. 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 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 What is the 90% confidence interval for the mean difference in pulse rates of men versus women? e lower bound is e upper bound is
