Help A statistics student is studying if there is a relationship Using the computer output, what is the equation of the
between the price of a used car and the number of least-squares regression line?
miles it has been driven. She collects data for 20 cars
of the same model with different mileage, and
9 -0.181 +24157 2x
determines each car's price using a used car website, O 9 = 24157.2 -0.181x
The analysis is given in the computer output.
O y = 2164.1 +0.024x
