A response variable,
Price,
is defined as the selling price of a used car. Three
predictor variables include,
Age,
the age of the car in years,
Mileage,
the
mileage of the car in thousands of miles, and
Cylinders,
the number of
engine cylinders. The estimated regression equation is:
Price
= 10,000 -
1800
Age
- 50
Mileage
+ 1200
Cylinders.
By how much will the price be reduced for each additional 10,000 miles on the car?
Can you explain how the answer is 500 or -500?
