Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of the comparison treatments. Each participant takes the assigned mediaction and his or her systolic blood pressure is recorded after 6 months on the assigned treatment. The data are as follows: Standard treatment Placebo New Treatment 124 134 114 111 143 117 133 148 121 125 142 124 128 150 122 115 160 128 Is there a difference in Mean systolic blood pressure among treatments? Run the appropriate test at a=0.05.
