Human Development Index 2019, part 2.

The United Nations Development Programme (UNDP) uses the Human Development Index (HDI) in an attempt to summarize in one number the progress in health, education, and economics of a country. The expected years of schooling is positively associated with a country’s income which represents the country’s economic progress. Can that be used to predict the HDI? Here is a scatterplot:

a) Would it be appropriate to fit a linear model to these data?

b) If you fit a linear model to the data, what do you think a scatterplot of residuals versus predicted HDI will look like?
