Display Data · Exercise 16

Use the two frequency tables to compare the life expectancy of males and females from 20 randomly selected countries. Include an overlayed 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 females compared to males?

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

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

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
