In Chapter 17, Exercise 33 we found a model for GDP per Capita from three country characteristics: Cell phones/100 people, Internet Users/100 people, and Primary Completion Rate. A look at leverage values and Cook€™s distance identifies three countries with high leverage (above 0.10) as Bahrain, Burkina Faso, and Israel and one country, Luxembourg, that stands as an outlier in Cook€™s distance.
On the next page are summary statistics for each variable in the model and the rows for those four countries.

a) Explain why each country was identified as a possible high influence point.
b) What might you consider doing next?
