3.40. Infant mortality rates (number of infant deaths, per 1000 live births) are reported by the UN.

In their 2006 report, the values for Africa had a five-number summary of min — 54,Q1 - 76, median - 81, Q3 = 101, max = 154.

The values for Western Europe had a five-number summary of min = 3,Q I = 4, median = 4,03 = 4, max = 5.

Sketch side-by-side box plots, and use them to describe differences between the distributions.

(The plot for Europe shows that the quartiles, like the median, are less useful when the data are highly discrete.)
