Question:

Consider predicting the per capita GDP (gross domestic product, in thousands of dollars), of a country, using x₁= carbon dioxide emissions per capita (in metric tons) and x₂= percent of country population not using the Internet. Based on data for several countries, the following computer output was obtained:
