d. Suppose, using standard medical treatment, that the mortality rate (r) of a certain disease is known to be

A. A manufacturer submits for approval a drug that is supposed to treat this disease. The FDA sets up the hypothesis to test the mortality rate for the drug as (1) Ho: r = A, Ha: r < A, a = 0.005 or (2) Ho: r = A, Ha: r > A, a = 0.005

a. If A = 0.95 which test do you think the FDA should use? Explain.

b. If A = 0.05 which test do you think the FDA should use? Explain.
