Question:

Predicted price in thousands of dollars = 17 - 0.8 (age in years)
This is the deterministic component of a regression model for predicting price on the basis of the age of the car. What factors might contribute to the random component? In other words, why might the price of the car he buys not fall exactly on this line?
