Data were collected on y = price of car (in dollars) and x = age of car (in years) for each car in a sample of 60 used Toyota Camrys. A scatterplot showed a negative linear relationship between x and y. The least squares regression line was fit and the r2 value was computed. If r2 = 0.55, which of the following is a correct statement?
answer choices
There is a very strong linear relationship between car price and number of miles driven.

For each additional mile driven, car price increases by approximately $0.55

Approximately 55% of the variability in car price can be explained by the linear relationship between car price and number of miles the car has been driven.

If the least-squares line is used to predict car price based on number of miles driven, predictions should be within $0.55 of the true price.
