A veterinarian is studying three different medications that could be used in the prevention of heartworm in young puppies. She has acquired for study four different litters of cocker spaniels, and 3 puppies were randomly selected from each litter. The three selected puppies from a litter were then randomly assigned to one of the four treatments. The data below represents the number of months after a single treatment before the initial onset of heartworm in the puppies for this randomized block design. a) Construct the ANOVA table for this experiment. b) Test the equality of the mean time to onset of heartworm for the three different medications at the .05 level. c) Using the 95% Tukey-Kramer procedure determine which of the treatment means are significantly different.
