Transcribed Image Text:A data set includes 103 body temperatures of healthy adult humans having a mean of 98.9°F and a standard deviation of 0.65°F. Construct a 99% confidence interval estimate of the mean
body temperature of all healthy humans. What does the sample sugest about the use of 98.6°F as the mean body temperature?
