Aphvsical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She randomlyr selected 51 men and 80 women to participate in the study. Each subject was required to step up and clown a 6-inch platform. The pulse of each subject was then recorded. The following results were obtained. (a) State the null and alternative hypotheses. Which of the following is correct? [:1 A. H9411: LIZ: Ha: u1 >p2 [:1 B. H9411: p2;Ha:u13'Ep2 [:1 5- Ho3l11= "23Ha3l'1'W2 (b) Identify the Pvalue and state the researcher's conclusion if the level of signicance was (I = [\"12 What is the Pvalue? P-value = E State the researcher's conclusion. Which of the following is correct? C: A. Reject HD. there is sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of women [:1 B. Fail to reject Ho: there is sufcient evidence to conclude that the mean step pulse of men was less than the mean step pulse of women [:1 C. Fail to reject H0: there is not sufcient evidence to conclude that the mean step pulse of men was less than the mean step pulse of women C: D. Reject HD. there is not sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of women to} What is the 98% confidence interval for the mean difference in pulse rates of men versus women? The lower bound is D. The upper bound is D. (Round to two decimal places as needed.) Interpret this result. [:1 A. 98% percent of the time the means are in the confidence interval. [:1 B. We are 93% condent that the mean difference is in the condence interval. [:1 C. We are 93% condent that the means are in the condence interval. O D. 98% percent of the time the mean difference is in the confidence interval.Two sample T for Men vs Women N Mean StDev SE Mean Men 51 112.4 11.2 1.6 Women 80 118.1 14.1 1.6 98% CI for mu Men - mu Women ( - 10.98, - 0.42) T-Test mu Men = mu Women (vs
