Exercise 4.3.5

Answers

E = {(C - 0)}^{2} + {(C - 8)}^{2} + {(C - 8)}^{2} + {(C - 20)}^{2} .

A^{T} = [\begin{matrix} 1 & 1 & 1 & 1 \end{matrix}]

and $A^{T} A = [4]$ . $A^{T} b = [36]$ and ${(A^{T} A)}^{- 1} A^{T} b = 9 =$ best height $C$ for the horizontal line. Errors $e = b - p = (- 9, - 1, - 1, 11)$ still add to zero.
