36. Mean Body Temperature Data Set 3 “Body Temperatures” in Appendix B includes 106 body temperatures of adults for Day 2 at 12 AM, and they vary from a low of 96.5°F to a high of 99.6°F. Find the minimum sample size required to estimate the mean body temperature of all adults. Assume that we want 98% confidence that the sample mean is within 0.1 °F of the population mean.
a. Find the sample size using the
b. Assume that σ = 0.62°F, based on the value of s = 0.62°F for the sample of 106 body temperatures.
c. Compare the results from parts (a) and (b). Which result is likely to be better?
