Question: Medicine and Clinical Studies A new drug designed to reduce fever (and relieve aches and pains) is being tested for efficacy and side effects. Ten patients entering a hospital with a high fever were selected at random. The temperature (in °F) of each patient was measured, the drug was administered, and two hours later the temperature was measured again. The data are given in the following table.

a. What is the common characteristic that makes these data paired?

b. Assume normality. Conduct the appropriate hypothesis test to determine whether there is any evidence that the new drug reduces the mean patient temperature after two hours. Use a = 0.05.

c. Find bounds on the p value associated with this hypothesis test.

d. What characteristic of the differences suggests that a hypothesis test will be significant?
