![Part 1 of 4
A pharmaceutical company claims their new diabetes medication results in less variance in a
patient's glucose level than if the patient were on no medication at all. An endocrinologist wishes to
test this claim. She divides participants randomly into two groups. Group A consists of 20 diabetics
who received the medication; group B consists of 26 diabetics who received a placebo. After two
weeks, the blood sugar level of each patient in each group was measured with the following results
(in mg/dL):
Group A:
77.8, 229.4, 199.9, 110.1, 180.2, 116.1, 139.7, 171.1, 37.4, 158.1, 88.4, 195.5, 246.1, 142.4, 178.1,
105.5, 179.6, 146.1, 78.8, 123.7
Group B:
124.5, 130.1, 136, 162.8, 113.4, 72.8, 142.6, 50.3, 179.8, 197, 230, 194.3, 171, 109.3, 114.4, 107.5,
