12. (6 pts) For a two-factor design that is analyzed using the model: Yijk = u + Ai + Bj + (AB)ij + Eijk Let SSModel(A, B,A*B) represent the model sum of squares that is obtained from the model with A, B, A*B in the mode and SSModel(A, B) represent the model sum of squares that is obtained from the model with A and B in the model. Similarly for SSModel(A) and SSModel(B). For a particular analysis, suppose SSTO=33.8, SSModel(A, B,A*B)=17.1, SSModel(A)=13.8, SSModel(B)=0.2, SSModel(A, B)=14.0. a. Compute the Type Ill sum of squares for the A*B interaction. b. Compute the Type I sum of squares for A
