Figure This!



Complete Solution:

In both 1970 and 1980, the difference in life expectancy was between 7 and 8 years.

Look at each pair of data points and find the difference in life expectancy for males and females. You can estimate the difference from the graph or measure it with a ruler. You can also use and index card or a sheet of paper and mark the difference to see which is greater. Then identify the years for which the greatest difference occurs. The greatest difference (between 7 and 8 years) appears in both 1970 and 1980.
