Drug 1 Drug 2 Drug 3 A clinical researcher is conducting a study to compare three blood sugar reduction drugs. We are looking to see which drug 20 7 29 leads to the most blood sugar level reduction. Thirty people with type-ll diabetes were randomly assigned to receive one of the 12 -15 17 three drugs. The level of blood sugar reduction after 90 days (in mg/dl) is displayed in the table. Assume that the group variances 8 22 0 are equal. 26 30 13 F = p= 9 19 36 10 -5 3 df. = 9 16 28 27 df = 21 Cohen's f = 4 18 40 32 14 31 What decision would we make regarding the null hypothesis that the three drugs have equivalent effects on blood sugar? 11 34 24 Reject Retain
