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. He divides participants randomly into two groups. Group A consists of 20 diabetics who received the medication; group B consists of 25 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: 149.5, 178.9, 145.8, 195.4, 97.4, 123.4, 128.8, 121.1, 189.7, 134, 125, 93.7, 222.9, 115.5, 188.9, 87.6, 132.6, 109, 201.3, 93.1 Group B: 152.5, 138.5, 188, 52.9, 186.6, 154.3, 193, 150.1, 187.1, 122.1, 167.1, 112.2, 197.5, 131.8, 115.6, 166.2, 108, 141.3, 110.2, 164.5, 189.4, 142.2, 174, 190, 171.3 Perform a hypothesis test using a 5% level of significance to test the pharmaceutical company's claim. Step 1: State the null and alternative hypotheses. Ho: Ha: 1 (So we will be performing a left-tailed v test.) Part 2 of 4 Step 2: Assuming the null hypothesis is true, determine the features of the distribution of test statistics. We will use a(n) F vv distribution with numerator degrees of freedom dfA and denominator degrees of freedom dfp = Ouertion Holpi O Dort to forum
