Solution :

1). The cost of the formula is given as :

$ 19,350 + $12 x

2). 95% $\text{confidence interval}$ for the prediction is :

$21430 - 1.96 \times 220 < \text{Yf} < 21430+1.96 \times 220$

$20998.8 < \text{Yf} < 21861.2$

$20999 < \text{Yf} < 21861$ (rounding off)

3). r = 0.92

Therefore, $r^2 = 0.8464$

That is 84.64 % of the variability in the moving cost is best explained by the number of moves.
