On a separate sheet of paper, draw a Lorenz Curve for the United States, using the 2017 values for income quintiles. Label each kink point carefully, and draw the diagonal equality Lorenz Curve. Calculate the Gini Coefficient, and show your work. This is a long and tedious math problem, where you find the areas of triangles, rectangles and trapezoids over and over to get the areas needed for the formula.
