Problem L5. (5 points} - For an experiment with fOUJ' treatments and number of reps given by 111 = 3, n2 2 4, n3 2 5, 1'14 2 3., the following models were proposed: I Cell means Model: yij 2 pi + 8,3,: I Effects Model: yij = p. i Ti; + eig- Answer the following questions: Write out the Design Matrix for the Cell Means Model Write out the Design Matrix for the Effects Models With no constraints Write out the Design Matrix for the Effects Models with the constraint: 1'4 2 0 For the Effects Model with no constraint express 1:; in terms of p. and #5 EDP-\"PF?\" For the Effects Model with the constraint 1'4 2 U express 7,- in terms of it and p\
