Human Body Temperatures (Example 12) A random sample of 10 independent healthy people showed the following body temperatures (in degrees Fahrenheit):

$98.5,98.299.0,96.3,98.3,98.7,97.2,99.1,98.7,97.2$ $98.5,98.299.0,96.3,98.3,98.7,$ $97.2,99.1,98.7,97.2$

Test the hypothesis that the population mean is not $98.6\text{°F,}$ using a significance level of $0.05$. See page 500 for guidance.
