Some Policy Advisors Have Argued That Education Should Be Subsidized $\sum _ { i = 1 } ^ { n } Y _ { i }$

question 25

Short Answer

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
