2. Background Automobile designers worried about the gasoline mileage a car would give Would it result in violation of Corporate Average fuel Efficiency regulations Weight of the car was the main concern The kind of factors that would affect were like a BLACK BOX to them The Goal is to get an equation and predict the mileage.
10. Do not forget the power GP1000M City= 11.7 + .0089 Weight (lb) +.088 Horsepower R2 from 77% to 84 % Horse power capture one third of residual variation with t statistic = 7.29
11. Scatter plot/ Residual plot Discreetness of response skewnessin the residual has reduced
17. Conclusion Weightand Horsepower are the important factors Powerto weight gives the better equation Prediction Interval [57.3-71.3]GP1000M=> [14.0-17.5] MPG
