The following table gives in years of cars and annual usage if X=36 compute the regression.
X | 40 | 34 | 28 | 30 | 44 | 38 | 31 |
Y | 32 | 39 | 26 | 30 | 38 | 34 | 28 |
Correct Answer
Let A = {-18,-9,0,9,18,27}
= {xn|xn = xn-1 + 9, x1 = -18 & i ≤ n ≤ 6}
or
A = {x|x is a multiple of 9 }
= {9x |x∈ [-2,3]}
