A sample of 106 body temperatures was found to have a mean of 98.20℉ and a standard deviation of 0.62℉. Use a 0.05 significance level to test the claim that the mean body temperature of the population is equal to 98.6℉ as is commonly believed. Is there sufficient evidence to conclude that the common belief is wrong?
