60 people volunteer to participate in an experiment to test the effectiveness of 4 different treatments (3 different drugs and a control). Since effectiveness of any drug depends heavily upon age, age is used as a blocking variable. The 60 volunteers are divided into 15 blocks of 4, based upon age. Within each block, the 4 treatments are randomly assigned. The control group mean was 81. The means of the 3 drug groups respectively were 72, 68, and 79 Note: from these and other particulars from the problem description, you can calculate SSdrug 19pts a) Fill in the following ANOVA table (MSerror and SStotal given) Two-way ANOVA Source of Variation DF SS MS = SS/DF F P-value Drug Age Error 220 Total 21670
