Explanation / Answer

By using some statisticalpackage we have the following regression analysis

Regression Analysis: Fuelversus Weight

The regression equationis
Fuel = 45.8 - 0.00550 Weight

weighs = 3000 lbs in theabove regression equation we have
Fuel = 45.8 - 0.00550 (3000)
      = 29.3
Therefore the best predicted highway fuel consumption amountin mi/gal for a car that weighs 3000 lbs is 238.2
