Climate change is a global challenge, and many countries have committed to reduce carbon emissions significantly before 2050. To understand the determinants of carbon dioxide emissions, Mr. Tan collected data on CO2 emissions (million tons), GDP (billion US$), population (million), energy use per capita (kg of oil equivalent), and share of electricity production from oil, gas and coal sources, in 2015 from 34 countries from World Development Indicators, and performed the regression analysis. The data can be found in the image uploaded.

(a) Describe the relationship between the CO2 emissions and the four (4) independent variables by writing down the linear equation. Interpret the coefficients to show how each of the independent variables impact CO2 emissions. Show regression output on excel.
