A data set includes body temperatures of healthy adult humans for which x= 98.2 and
s=0.64 F. Complete parts a) and b) below

a) what is the best point estimate of the
mean body temperature of all healthy humans? The best point estimate is F.

b) Using the sample statistics, construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. Do the confidence
interval contain 98.6 F. What does the sample suggest about the use of 98.6 as
the mean body temperature. What is the confidence interval estimate of the population mean u? F<u<F. Round to three places as needed. Do the confidence interval limits contain 98.6 F. What does this suggest about the use of 98.6 as the mean body temperature?

  1. a. The best point estimate is 98.2

    b. 98.2 - 2.575 * 0.64/sqrt(n) < u< 98.2 + 2.575 * 0.64/sqrt(n)

    This suggests that the mean body temperature could be lower than 98.6 ̊F.
