Question

A data set includes 107 body temperatures of healthy adult humans for which x-98.7°F and s-072?F. Complete parts (a) and (b) below. Click here to view a t distribution table a. What is the best point estimate of the mean body temperature of all healthy humans? The best point estimate isF. Type an integer or a decimal.) b Using the sample statistics, construct a 99% confidence interval estimate of the mean body temperature o a healthy humans. Do the confidence interval mits contain 98.6 F? What does the sample suggest about the use of 98.6 F as the mean body temperature? What is the confidence interval estimate of the population mean ?? Round to three decimal places as needed.) Do the confidence interval limits contain 98.6 F? O No O Yes What does this suggest about the use of 98.6 F as the mean body temperature?

Explanation / Answer

The statistical software output for this problem is:

One sample T summary confidence interval:
? : Mean of population

99% confidence interval results:

Hence,

a) Best point estimate = 98.7

b) 99% confidence interval:

98.517 < ? < 98.883

Yes

It suggests that this temperature is likely to occur.

Mean Sample Mean Std. Err. DF L. Limit U. Limit ? 98.7 0.069605027 106 98.517425 98.882575
