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 expectancyy (in years) are given. These data are displayed in the Figure 1 scatter M- 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", may aid in calculations.) Birthrate, x Female life (Eizegetf expectancy, y 1000 pop.)
