A data set includes 110 body temperature of healthy adult humans for which x=98.1 degrees F and s=0.64degrees F. complete parts(a) and (b) below click here to view a 1 distribution table click here to view page 1 of the standard normal distribution click here to view page 2 of the standard normal distribution

Solution

a) The best estimate of the mean body temperature is the sample mean = 96.1F
b) Confidence interval for population mean (Mu) is
sample mean +/- confidence coefficient*standard error of mean
96.1+/- 2.575*0.64/sqrt 110
96.1+/- 0.1
lower limit is 96.1-0.1= 96
upper limit is 96.1+0.1= 96.2
The CI is 96< Mu < 96.2

NO, the confidence interval doesn\'t contain 96.6F
The sample suggests that the use of 96.6F is NOT valid or reliable.
