ANOVA

A large health maintenance organization is interested in the prescribing patterns of physicians. Suppose that we selected a random sample of three patients treated for four diagnoses by three physicians.
Physician 
Diagnosis A B C
1 11,7,9 8,6,7 5,4,7
2 14,10,11 10,9,8 6,8,7
3 4,5,3 5,5,6 3,4,2
4 10,9,7 6,7,4 5,6,3
If 0.05, determine whether differences among the treatment, block, and interactive effects are significant.
