Researchers record the fuel consumption of a car y (in miles per gallon) at various speeds x (in miles per hour). Using software, they determine that the regression line of their data is ŷ = = 70.243 0.0274x - If the observed fuel consumption of the car was y = 49 mpg while moving at a speed of x = 20 mph, what would be the error (i.e., residual) in the predicted fuel consumption at this speed found with the regression line? Round your answer to three decimal places.
