A psychologist would like to examine the effects of a new drug on the activity level of animals. Three samples of rats are selected with n = 5 in each sample. The rats in the first sample serve as a control and do not get any of the drug. The rats in the second group receive a small dose, and the rats in the third group each get a large dose of the drug. The researcher records the activity level for each animal. Do these data indicate any significant differences among the three groups? Show all five steps, but you do not need to carry out post hoc analyses. Use alpha = .05. %3D Controls Small dose Large dose 2 15 2 12 3 2 3 2 2 12 1 1 3 SS = 4 SS = 2 SS = 6 EX2 = 9 EX2 = 22 EX2 = 51 G = 30
