Question: The data in Example, on body temperature for young adults, was part of a larger set of body temperatures taken on 100 adults at a blood donor center. The data are in the file bodytemp on the website for this book. The Minitab output below shows the results of the "2-sample t" procedure for comparing the body temperatures of males and females.
a. Give the null and alternative hypotheses using symbols.
b. What is the value of the test statistic t?
c. Identify the numbers that were used to compute the t-statistic, and verify that the reported value is correct.
d. What conclusion would be made using a .05 level of significance? Write the conclusion in statistical terms and in the context of the problem.
Example: Normal Body Temperature for Young Adults What is normal body temperature? A paper published in the Journal of the American Medical Association presented evidence that normal body temperature may be less than 98.6 degrees Fahrenheit, the long-held standard (Mackowiak et al., 1992).
