Problem 21

Comparing Step Pulses 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 51 men and 70 women to participate in the study. Each subject was required to step up and down onto a 6-inch platform for 3 minutes. The pulse of each subject (in beats per minute) was then recorded. After the data were entered into Minitab, the following results were obtained

(a) State the null and alternative hypotheses.

(b) Identify the P-value and state the researcher’s conclusion if the level of significance was  = 0.01.

(c) What is the 95% confidence interval for the mean difference in pulse rates of men versus women? Interpret this interval.

Step-by-Step Solution:

Step 1 of 5) Comparing Step Pulses 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 51 men and 70 women to participate in the study. Each subject was required to step up and down onto a 6-inch platform for 3 minutes. The pulse of each subject (in beats per minute) was then recorded. After the data were entered into Minitab, the following results were obtained (a) State the null and alternative hypotheses. (b) Identify the P-value and state the researcher’s conclusion if the level of significance was = 0.01. (c) What is the 95% confidence interval for the mean difference in pulse rates of men versus women Interpret this interval. For example, we obtain a simple random sample of individuals and ask them to disclose their number of years of education.
