The following graph is based on one that appeared in an Arizona Republic newspaper article entitled "Hand That Rocked Cradle Turns to Work as Women Reshape U.S. Labor Force." The graph depicts the labor force participation rates for the years 1960, 1980, and 2000.
a. Cover the numbers on the vertical axis of the graph with a piece of paper.

c. Now remove the piece of paper from the graph. Use the vertical scale to find the actual ratio of the percentages of 35- to 44-year-old women in the labor force for 1960 and 2000.
d. Why is the graph potentially misleading?
e. What can be done to make the graph less potentially misleading?
