Pulse Rates A physician wants to develop criteria for determining whether a patient’s pulse rate is atypical, and she wants to determine whether there are significant differences between males and females. Using the sample pulse rates in Data Set 1 in Appendix B, the male pulse rates can be summarized with the statistics n 5 40, 5 69.4, s 5 11.3. For females, the statistics are n 5 40, 5 76.3, s 5 12.5.

a. Construct a 95% confidence interval estimate of the mean pulse rate for males.

b. Construct a 95% confidence interval estimate of the mean pulse rate for females.

c. Compare the preceding results. Can we conclude that the population means for males and females are different? Why or why not?
