Now suppose the correlation coefficient for the relationship between a country’s adolescent birth rate (i.e., the rate at which teenage girls give birth) and life expectancy works out to be −0.71. What can we conclude from the value of that correlation coefficient?
I. The association between the adolescent birth rate and life expectancy is strong and positive (as the adolescent birth rate increases, life expectancy increases as well).
II. The association between the adolescent birth rate and life expectancy is strong and negative (as the adolescent birth rate increases, life expectancy decreases).
III. The two variables are in no way related to one another.
IV. None of the above.
