The following scenario examines the relationship between marginal and average values. Suppose
Mina is a high school basketball player. The following table presents their game-by-game results
for foul shots.On the following graph, use the orange points (square symbol) to plot Mina's foul-
shooting percentage for each game individually, and use the green points (triangle symbol) to plot
Mina's overall average foul-shooting percentage after each game. Note: Plot your points in the
order in which you would like them connected. Line segments will connect the points
automatically.You can think of the result in any one game as being Mina's marginal shooting
percentage. Based on your previous answer, you can deduce that when Mina's marginal shooting
percentage is below the average, the average must be You can now apply this analysis to
production costs. For a U-shaped average total cost (ATC) curve, when the marginal cost curve is
below the average total cost curve, the average total cost must be . Also, when the marginal cost
curve is above the average total cost curve, the average total cost must be . Therefore, the
marginal cost curve intersects the average total cost curve
