Question
Below are bivariate data giving birthrate and life expectancy information for each of twelve countries. For each of the countries, both the number of births x per one thousand people in the population and the female life expectancy y (in years) are given. These data are displayed in the Figure 1 scatter plot. Also given are the products of the birthrates and female life expectancies for each of the twelve countries. (These products, written in the column labelled "xy," may aid in calculations.) Birthrate, x (number of births per 1000 pop.)
