3. The high-low estimate of fixed costs is $170.90 lower than the estimate
provided by least-squares regression. The high-low estimate of the
variable cost per unit is $1.82 higher than the estimate provided by
least-squares regression. A straight line that minimized the sum of the
squared errors would intersect the Y-axis at $1,170.90 instead of
$1,000. It would also have a flatter slope because the estimated variable
cost per unit is lower than the high-low method.
