A college professor decided to grade his tests on a curve using the following criteria.
Given the following stem-and-leaf plot, find out how many students will receive each grade.
Based on a 10-point scale where 90-100 is an A, 80-89 is a B, 70-79 is a C, 60-69 is a D and below 59 is an F, is this professor’s curve fair or unfair? Who benefits from the curve? Who is hurt by the curve?
