(Show a excel graph)show two scatter plots, one for each country, that shows non-Income HDI (y-axis) relative to its GNI per capita (x-axis) across all years. Make sure you graph each country's nonIncome HDI values against that same country's GNI per capita values. To each scatter plot, add a linear trendlines and have Excel display both equations on the chart.

5.What is the equation for the linear trendline for each country? For each country, is the relationship between non-Income HDI and GNI per capita positive or negative? Now calculate the difference between I(GNI) and HDI for each country in each year. 3

6. For each country, what is the average difference between I(GNI) and HDI? What does this tell you about each country's income relative to its performance on the other development indicators?

7. Is the World Bank's income criterion a useful way of classifying countries by their development levels? Why or why not?
