Below are bivariate data giving birthrate and life expectancy information for each of twelve countries. For each rthe
countries, both the number of births x per one thousand people in the population and the female life expectanc
years) are given. These data are displayed in the Figure 1 scatter plot. Also given is the product of the birthrate and the
female life expectancy for each of the twelve countries. (These products, written in the column labelled "xy", n
calculations.)
