The following equation was developed relating yearly income (y in $1,000s) of 30 individuals with their age (x1) and their degree (x2) (0 if not having a Bachelor degree and 1 if having a Bachelor degree). y^ = 30 + 0.7x1 + 3x2. SST = 1,200 and SSE = 384. The equation y^ = 30 + 0.7x1 + 3x2 is

In a regression analysis involving 30 observations, the following estimated regression equation was obtained. $$\hat{y}=17.6+3.8 x_{1}-2.3 x_{2}+7.6 x_{3}+2.7 x_{4}$$ a. Interpret $b_{1}, b_{2}, b_{3},$ and $b_{4}$ in this estimated regression equation. b. Predict $y$ when $x_{1}=10, x_{2}=5, x_{3}=1,$ and $x_{4}=2 .$
