Price = -9874.1 + 1036.3sqrmtr+ 17.503lotsize + 12086bdrms N= 1, R-square = 0.6571 2. 12086 3. 41102.4. Different answer as there is now an additional dependant variable to consider 4. 65.71% 5. $366213.198 6. $366610.9 => u= $46610.90 According to number it is underpriced however, since R-square does not equal to 1 this means there are other factors not accounted for that affects the changes in price. For it to be exactly 320000 the disturbance has to equal 0, e(u|x)=0. Therefore in reality no solid it to be exactly 320000 the disturbance has to equal 0, e(u|x)=0....
