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. Use the sample pulse rates below.
Male Female
96 72
64 88
72 104
64 72
84 64
60 88
76 84
76 96
76 96
68 124
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?
