200 subjects, all with common colds, participate in a trial for a new cough medicine. 100 subjects are randomly placed in the treatment group, while the other 100 are placed in the control group and given a placebo. A short while later, evaluators (who aren’t told which group each subject was in until after their evaluation) determine that 45% of subjects in the treatment group are coughing less, compared to 36% of subjects from the control. Is the medicine effective?
