Researchers performed a study to address the question of whether
the mean body temperature of humans is 98.6 degrees °F.
Among other data, the researchers obtained the body
temperatures of 40 healthy humans, as provided in the accompanying
data table. 97.9, 97.5, 99.0, 98.1, 98.7, 98.8, 97.6, 98.5, 98.5,

A medical researcher attempted to learn if a disease is
accompanied by an increased in body temperature. She measured the
body temperature of 12 people diagnosed as having the disease and
obtained the following temperatures (in degrees F): 99.3, 99.1,
100.4, 98.4, 98.2, 98.9, 99.7, 100.1, 100.7, 99.0, 98.8, 99.2. Does
the mean body temperature of these individuals differ from a
hypothesized population mean of 98.6 degree F? Use a two-tailed
test and a 0.05 significance level

A medical researcher believes that a drug changes the body's
temperature. Seven test subjects are randomly selected and the body
temperature of each is measured. The subjects are then given the
drug, and after 30 30 minutes, the body temperature of each is
measured again. The results are listed in the table below. Is there
enough evidence to conclude that the drug changes the body's
temperature? Let d=(body temperature after taking drug)−(body
temperature before taking drug) d = (body temperature...

In a 1868 paper, German physician Carl Wunderlich reported based
on over a million body temperature readings that the mean body
temperature for healthy adults is 98.6° F. However, it is now
commonly believed that the mean body temperature of a healthy adult
is less than what was reported in that paper. To test this
hypothesis a researcher measures the following body temperatures
from a random sample of healthy adults. 98.0, 98.3, 98.5, 98.5,
97.3, 98.4
