# Question

The given data represent the fossil-fuel carbon dioxide (CO2) emissions (in thousands of metic tons) of the top 10 emitters in 2007.

(a) Determine the mean CO2 emissions of the top 10 countries.

(b) Explain why the total emissions of a country is likely not the best gauge of CO2 emissions; instead, the emissions per capita (total emissions divided by population size) is the better gauge.

(c) Determine the mean and median per capita CO2 emissions of the top 10 countries. Which measure would an environmentalist likely use to support the position that per capita CO2 emissions are too high? Why?
