Explanation / Answer

a) The sample mean (x) is a point estimate of the population mean,

So 98.3 Degree F is the best point estimate.

b) 99% confidence interval is

Xbar= 98.3
t critical value = 2.62
sM = (0.73)^2/103) = 0.07
= M ± t(sM)
= 98.3 ± 2.62*0.07
= 98.3 ± 0.189

Sample mean=98.3, 99% CI [98.111, 98.489].

You can be 99% confident that the population mean () falls between 98.111 and 98.489.

No the confidence interval limit doesn't contain 98.6 degree F.

Note: Please confirm me that sample mean is 98.3 Degree F.
