A data set includes 106 body temperature of healthy adult humans for which /x = 98.7°F and s = 0.66°F Complete parts (a) and (b) below.

a.What is the best point estimate of the mean of body temperature of all healthy humans?
The best point estimate is ______ °F?
(Type an integer or a decimal)

b.Using the sample statistics, construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. Do the confidence interval limits contain 98.6°F as the mean body temperature?

What is the confidence interval estimate of the population mean µ?

_____°F < µ < _____ °F
(Round to three decimal places as needed)

Do the confidence interval limits contain 98.6°F?
o Yes
o No

What does this suggest about the use of 98.6°F as the mean body temperature?

o A. This suggest that the mean temperature could be higher than 98.6°F
o B. This suggest that the mean temperature could be lower than 98.6°F
o C. This suggest that the mean temperature could very possibly be 98.6°F


Please show your work step by step so that I can see how it was done for other problems.
Thank you.

a) The best point estimate of population mean is the sample mean = 98.7
b) Confidence interval for population mean (Mu) is
sample mean +/- confidence coefficient*standard error of the mean
98.7 +/- 2.575*0.66/sqrt 106
98.7 +/- 0.165
lower boundary is 98.7 - 0.165 = 98.535
upper boundary is 98.7 + 0.165 = 98.865
i) 98.535 < Mu < 98.865
ii) Yes
iii) A
[otherwise C)
