Histograms, Frequency Polygons, and Time Series Graphs · Exercise 9

Use the two frequency tables to compare the life expectancy of men and women from 20 randomly selected countries. Include an overlaid frequency polygon and discuss the shapes of the distributions, the center, the spread, and any outliers. What can we conclude about the life expectancy of women compared to men?

$$\begin{array}{cc}\text{Life Expectancy at Birth – Women}& \text{Frequency}\\ \text{49–55}& \text{3}\\ \text{56–62}& \text{3}\\ \text{63–69}& \text{1}\\ \text{70–76}& \text{3}\\ \text{77–83}& \text{8}\\ \text{84–90}& \text{2}\end{array}$$

$$\begin{array}{cc}\text{Life Expectancy at Birth – Men}& \text{Frequency}\\ \text{49–55}& \text{3}\\ \text{56–62}& \text{3}\\ \text{63–69}& \text{1}\\ \text{70–76}& \text{1}\\ \text{77–83}& \text{7}\\ \text{84–90}& \text{5}\end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
