Data on the fuel consumption yy of a car at various speeds xx is
given. Fuel consumption is measured in mpg, and speed is measured
in miles per hour. Software tells us that the equation of the
least‑squares regression line
is^y=55.3286−0.02286xy^=55.3286−0.02286xUsing this equation, we can
add the residuals to the original data.
