use the below data to do the following. group A: 7,5,4 groups B: 2,1,2 group c: 10,13,9 group d: 20,18,23. 1) compute group specific mean outcome. 2) compute deviation for each subject's outcome from his or her corresponding group specific mean. 3) compute the sum total of deviations for each group. 4) for each subject, compute the sum of the subject's corresponding group specific mean and subject's deviation. 5) does the sum calculated for each subject in part 5 equal to the observed outcome for that subject? 6) compute the overall grand mean. 7) compute deviation for each group mean from the overall mean. 8) for each subject compute the sum overall grand mean, deviation group mean from the overall mean, deviation for each subject's outcome from their corresponding group specific mean. 9) is the sum calculated for each subject in part 8 equal to the observed outcome for that subject
