hypertension trial is mounted, and 12 participants are randomly assigned to receive either a new medication or a placebo. Each participant takes the assigned medication and their systolic blood pressure, in mm Hg, is recorded after 6 months on the assigned medication. The data are shown in Table 7..9. Is there a difference in mean systolic blood pressure between treatments? Run the appropriate test at α = 0.05.
