Normal (or average) body temperature of humans is often thought to be 98.6°F. Is that number really the average body temperature for human males? To test this, we will use the MaleTemps data set (available from the textbook website) from the previous exercise.
a. Write out the null and alternative hypotheses for our test in words or in symbols.
b. You should have found (in the previous exercise) the sample mean body temperature for the 65 males in our sample to be 98.105°F and the standard deviation to be 0.699°F. Use the Th eory-Based Inference applet to find and report a standardized statistic (t-statistic) and a p-value for the test.
c. Based on your p-value, write out a conclusion, being sure to include justification.
d. Th e data did not come from a random sample; rather it came from a convenience sample of healthy adults that were involved in a vaccine study. Given that information, to what population do you think we can generalize our results?
