Use R to run a simple OLS regression with the natural log of CO2 as your dependent variable and the natural log of real GDP per capita as your explanatory variable. Specifically, run the following models:

You will have to take the natural logs of GDPpc and CO2 using R!

ln(CO2) = ???? ???? + ???? ???? ????????(????????????????????????) + ???? (Eq.1)

a. Provide your R output and write out your estimated regression equation.

b. What is the associated degrees of freedom and state whether standard normal critical values can be used.
