Exercise 4.3 Verify that the estimate of +i is yi and that the algebraic formulas

Exercise 4.3 Verify that the estimate of μ +αi is ¯ yi· and that the algebraic formulas for the sums of squares in the ANOVA table are correct.

Hint: To find, for example, Y (M−[1/n]Jn n )Y =YMαY, use Exercise 4.2 to get MαY and recall that YMαY = [MαY] [MαY].
