Question: An experiment was performed to determine if a new educational program given by pharmacists could reduce the prescribing of a widely used analgesic that had been proven to be inferior to aspirin. The physicians were randomly assigned to either control (n = 142) or the new educational program (n = 140), and their prescriptions of the analgesic were monitored from medical records. After the education program, 58 of the physicians in the control group prescribed the analgesic and 42 in the education group. Test for no difference in the proportion prescribing the analgesic at the α = .05 level.
