A) Generic drugs are lower-cost substitutes for band name drugs. Before a generic drug can be sold in the United States, it must be tested and found to perform equivalently to the brand-name product. The U. S. Food and Drug Administration (FDA) is now supervising the testing of a new generic antifungal ointment. The brand-name ointment is known to deliver a mean of 3.5 micrograms of active ingredient to each square centimeter of skin.
As part of the testing, seven subjects apply the ointment. Six hours later, the amount of drug that has been absorbed into the skin is measured. The amounts, in micrograms, are
2.6 / 3.2 / 2.1 / 3.0 / 3.1 / 2.9/ 3.7
Is there sufficient evidence that the mean amount absorbed differs from 3.5 micrograms? Use the alpha = 0.01 level of significance.
B) A consumer products safety group wants to challenge the results of the study. They say that the data used may not be reliable. How would you respond to them?
