The following regression model was fit to a set of data Y 14
     The following regression model was fit to a set of data:  Y\" 1.45 + 12.51 x  Suppose the actual value of y is 27 when x = 6. Find the residual ei.    
 
  
  Solution
(Y-Y\')^2 = 2451.24
| X | Y | Y\' = 1.45+12.51(x) | Y-Y\' | (Y-Y\')^2 | 
| 6 | 27 | 76.51 | 27-76.51 = -49.51 | 2451.24 |
