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 96 64 88 64 84 84
68 64 68 64 Female 68 84 104 60 76 88 96 76 72 124 a. Construct a
95% confidence interval estimate of the mean pulse rate for males.
___<μ<___ (Round to one decimal place as needed.) b.
Construct a 95% confidence interval estimate of the mean pulse rate
for females. ___<μ<___ (Round to one decimal place as
needed.) c. Compare the preceding results. Can we conclude that the
population means for males and females are different? A. Yes,
because the two confidence intervals do not overlap, we can
conclude that the two population means are different. B. Yes, the
population mean for males appears to be greater than the population
mean for females. C. Yes, the population mean for females appears
to be greater than the population mean for males. D. No, because
the two confidence intervals overlap, we cannot conclude that the
two population means are different. A physician wants to develop
