Explanation / Answer

sample size i.e n = 100

sample mean i.e x = 98.1

sample standard deviation i.e s = 0.64

standard deviation of population mean = s/n0.5 = 0.64/1000.5 = 0.64/10 = 0.064

99% confidence interval of normal distribution is (mean-2.58*sd, mean+2.58*sd)

99% confidence interval of mean body temperature is (98.1 - 2.58*0.064, 98.1 + 2.58*0.064)

i.e (97.9349 oF, 98.2651 oF)

98.6oF is to the right of of 99% confidence interval so this suggests that mean body temperature could be lower than 98.6oF
