The midrange is calculated as the average of the maximum and minimum values in the data set. The maximum value is $32.95 and the minimum is $18.95. The midrange is ($32.95 + $18.95) / 2 = $25.95. The range, however, is the difference between the maximum and minimum values, which is $32.95 - $18.95 = $14.
