A data set includes 109 body temperatures of healthy humans for which x- bar =98.2°F and s= 0.62°F. Complete parts a and b below.

A. What is the best point estimate of the mean body temperature of all healthy humans?

B. Using the sample statistics, construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. Do the confidence interval limits contain 98.6°F? What does the sample suggest about the use of 98.6°F as the mean body temperature? What is the confidence interval estimate of the population mean. (Round to three decimal places is needed) Do the confidence interval limits contain 98.6°F? (Yes or No) What does this suggest about the use of 98.6°F as the mean body temperature?
