Select a correct multiple regression equation that can be used to analyze the data for a two-factorial design with two levels for factor A and three levels for factor B. Define all variables. I. E(y) = Bo + 3121 + 32x2 + 8323, where 1 = 1 if level 2 for factor A, x1 = 0, if level 1 for factor A; 2 = 1 if level 2 for factor B, x2 = 0, otherwise; 3 = 1 if level 3 for factor B, x3 = 0, otherwise. II. E(y) = Bo + B121 + 32x2 + 8321 2 + B4X123, where 1 = 1 if level ? for factor A, x1 = 0, if level 1 for factor A; Activity Frame 2 = 1 if level 2 for factor B, x2 = 0, otherwise; 23 = 1 if level 3 for factor B, x3 = 0, otherwise. II. E(y) = Bo + 3121 + 32x2 + 8323 + B42122 + 352123, where x1 = 1 if level 2 for factor A, x1 = 0, if level 1 for factor A; x2 = 1 if level 2 for factor B, x2 = 0, otherwise; 23 = 1 if level 3 for factor B, x3 = 0, otherwise. IV. E(y) = Bo + B121 + 32x2 + 832122 + BAX123 + 85202 23, where 1 = 1 if level 2 for factor A, pif level 1 for factor A; aif level 2 for factor B, xotherwise
