You are part of a government task force evaluating whether new models of cars will meet fuel efficiency standards set out by the newly signed climate bill. You have run an ANCOVA model that predicts fuel efficiency (in miles per gallon) as a function of vehicle weight (measured in thousands of lbs, where a value of 2.5 would correspond to 2,500 lbs), horsepower, and number of cylinders in the car (cylinders is a factor in this model with 3 levels: 4 cylinders, 6 cylinders, and 8 cylinders).

You are part of a government task force evaluating whether new models of cars will meet fuel efficiency standards set out by the newly signed climate bill.

You have run an ANCOVA model that predicts fuel efficiency (in miles per gallon) as a function of vehicle weight (measured in thousands of lbs, where a value of 2.5 would correspond to 2,500 lbs), horsepower, and number of cylinders in the car (cylinders is a factor in this model with 3 levels: 4 cylinders, 6 cylinders, and 8 cylinders).

Your analysis tells you the following;

The mean miles per gallon of all cars analyzed is 20.09
The mean weight of all cars analyzed is 3.217 thousand lbs
The mean horsepower of all cars analyzed is 146.7
The regression coefficient for weight is -3.18 miles per gallon per additional thousand lbs
The regression coefficient for horsepower is -0.023 miles per gallon per additional unit of horsepower
Cars with 4 cylinders get 2.13 more miles per gallon, on average, than the average car

Toyota is considering making a new vehicle that weighs 1.835 thousand pounds, has 65 horsepower, and has 4 cylinders. Calculate the predicted miles per gallon for this potential new car, based on the existing model
