A graduate student realized that the blood pressure study above in Question E should have had a placebo condition in which a third group was given a pill just as the people in the Drug condition were, but where the pill is not Drug D(e.g., a sugar pill). So she designed a new experiment with three conditions -- Drug, No Drug and Placebo. To perform the experiment, the graduate student randomly assigned 15 people into the three groups so that each group has 5 people. After one month of treatment, she measured the systolic blood pressure of all 15 people. The following are the data: No Drug 133 Drug 142 135 137 149 131 Placebo 140 139 134 145 147 120 117 141 115 = no = 5 nND = 5 nplacebo = 5 Mp = 140.8 MND = 123.2 Mplacebo = 141 = =
