Finding Confidence Intervals. In Exercises 9–16, assume that each sample is a simple random sample obtained from a population with a normal distribution.

Body Temperature Data Set 3 “Body Temperatures” in Appendix B includes a sample of 106 body temperatures having a mean of \(98.20^{\circ} \mathrm{F}\) and a standard deviation of \(0.62^{\circ} \mathrm{F}\) (for day 2 at 12 AM). Construct a 95% confidence interval estimate of the standard deviation of the body temperatures for the entire population.

Text Transcription:

98.20^\circ\F
