A medical researcher wants to determine whether a drug changes the body’s temperature

1. A medical researcher wants to determine whether a drug changes the body’s temperature. Seven test subjects are randomly selected, and the body temperature (in degrees Fahrenheit) of each is measured. The subjects are then given the drug and, after 20 minutes, the body temperature of each is measured again. The results are listed below. At a = 0.05, is there enough evidence to conclude that the drug changes the body’s temperature? Assume the body temperatures are normally distributed.

a. Identify the claim and state H0 and Ha.

b. Identify the level of significance a and the degrees of freedom.

c. Find the critical values and identify the rejection regions.

d. Calculate d and sd.

e. Find the standardized test statistic t. Sketch a graph.
