In sub-Saharan Africa, more than half of mothers lose at least one child before the child’s first birthday. Below are data on 36 countries in the region, giving country, infant mortality, per capita income (in U.S. dollars), percentage of births to mothers under 20, percentage of births to mothers over 40, percentage of births less than two years apart, percentage of married women using contraception, and percentage of women with unmet family planning need.
(a) Make a scatter diagram of InfMort and income.
(b) Draw (by eye) the line that appears to best fit the data.
(c) What effect do you suppose that the two outliers have on predicted income?
