A clinical trial is run to assess the efficacy of a new drug to reduce high blood pressure. Patients with a diagnosis of hypertension (high blood pressure) are recruited to participate in the trial and randomized to receive either the new drug or placebo. Participants take the assigned drug for 12 weeks and their blood pressure status is recorded. At the end of the trial, participants are classified as still having hypertension or not. The data are shown here: Group Number Randomized Number of Hypertension at 12 Weeks Placebo 50 18 New Drug 50 30 What is the prevalence of hypertension at the end of the trial? A)48% B)18% C)30% D)12%
