Body temperatures (F) are taken from 38 subjects at 8 AM on the same day.

Excel output follows.

Test the claim that the body temperature is significantly different than 98.6 F, a common body temperature claim.

a. Write the null and alternative hypotheses

b. Show how to find the test statistic by hand. Note that you will need to use the mean and standard deviation from the Excel printout below.

c. Identify the appropriate P-value from the Excel print out below. If necessary, convert the P-value into decimal form, written to three significant digits.

d. Is there sufficient evidence to support the claim that the body temperatures are significantly

different than 98.6 F? Explain your answer.
