Go to the World Bank Development Indicators data and make a graph in the graph tab for the "Mortality rate, infant (per 1,000 live births)." Add “High income" and “Low income” country groups to the graph.Note: This is a separate indicator from the one mentioned in the lecture.Approximately how much higher or lower is the 2013 infant mortality rate in high income countries compared to low income countries? Hint: divide the high income country rate by the low income country rate.
