For the scenario in Problem 1(b),
a. Determine the required sample size for power levels ranging from 0.6 to 0.9, in increments of 0.10. Plot the sample size versus power. Comment on the observed relationship.
b. Determine the required sample size for absolute differences in proportions of patients who report side effects, ranging between 0.01 and 0.10, in increments of 0.01. Comment on the observed relationship.
