question 26

Essay

Some policy advisors have argued that education should be subsidized in developing
countries to reduce fertility rates.To investigate whether or not education and fertility
are correlated, you collect data on population growth rates (Y)and education (X)for 86
countries.Given the sums below, compute the sample correlation: $$\sum _ { i = 1 } ^ { n } Y _ { i } = 1.594 ; \sum _ { i = 1 } ^ { n } X _ { i } = 449.6 ; \sum _ { i = 1 } ^ { n } Y _ { i } X _ { i } = 6.4697 ; \sum _ { i = 1 } ^ { n } Y _ { i } ^ { 2 } = 0.03982 ; \sum _ { i = 1 } ^ { n } X _ { i } ^ { 2 } = 3,022.76$$
