- For recent UN data on several nations, a regression of annual
carbon dioxide emissions on gross domestic product (GDP) has a
correlation of 0.786. With average life expectancy added as a
second independent variable, the multiple correlation is 0.787.
- Explain how to interpret the multiple correlation.
- Report a measure of model fit for both models and explain what it means in each case. For predicting carbon dioxide emissions, did adding life expectancy do much to increase model fit?

Carbon dioxide (CO2) emissions are widely believed to be a
driver of global climate change. In this problem set you will use
cross-section data to test what drives countries’ “carbon
footprints,” that is, their CO2 emissions. Is it population, or is
income the bigger culprit?
The data set “CO2 by country 2010 sh S17” contains data on a
sample of countries’ CO2 emissions, in kilotons; population, in
millions; and gross national income (GNI), in millions of US
dollars, for the...

Q3. A company in the field of fast moving consumer goods has launched several new products in recent years. The sales manager has to provide a forecast for sales in the next quarter. These forecasts are used to draw up an initial production plan, which is updated daily as new data becomes available. To provide these forecasts, the sales manager has conducted regression analysis but needs your advice on its interpretation. Extracts from the Excel regression analysis for products A...
