Leonard is studying the relationship between the fuel efficiency in miles per gallon (mp3), y, and the speed in miles per hour (mph), x, of his car. He collected data for
8 different speeds and found a linear model that best fit his data: y = 18.46+0.16%. To analyze the fit of his function, he found the residuals and created the following
residual plot.
