Confidence Interval for the population mean.
The given data set includes 106 body temperatures for which x= 98.20F and s= 0.62F. Construct a 99 percent confidence interval estimate of the mean body temperature of all healthy humans. Do the confidence interval limits contain 98.6F? What does the sample propose about the use of 98.6F as the mean body temp?
