The estimated regression equation is

Y = b0 + b1X1 + b2X2 + e

E(Y) = b0 + b1X1 + b2X2

= 12.924 - 3.682 X1 + 45.216 X2

= 4.425 + 2.63 X1 + 12.56 X2

2. A regression model involving 4 independent variables and a sample of 15 periods resulted in the following sum of squares. SSR = 165; SSE = 60. The coefficient of determination is

1. 0.3636
2. 0.7333
