Researchers at a veterinary hospital wish to test a new drug developed for treating degenerative joint disease (DJD) in dogs. A group of 30 Great Danes, 50 Labradors, and 40 Mastiffs is to be used. The researchers randomly assign 15 of the Great Danes, 25 of the Labradors, and 20 of the Mastiffs to the traditional drug for treatment. The remaining dogs are assigned to the new drug. The major reason for separate assignment for each breed of dog is that
A) This is a large study with 120 dogs.
B) This design uses matched pairs to detect the new-drug effect.
C) The new drug may affect Great Danes, Labradors, and Mastiffs differently.
D) The new drug may affect dogs with DJD differently than dogs without DJD.
E) There must be an equal number of dogs in each of the two treatment groups.
