Data on three variables have been collected for 15 nations. The variables are fertility rate (average number of children born to each woman), education for females (expressed as a percentage of all students at the secondary level who are female), and percent of married women ages 15-49 using all forms of contraception.

Compute r and r2 for each combination of variables.
