24. Carbon footprint: Carbon dioxide [C(33) is produced by burning fossil fuels such as oi and natural gas, and has been connected to global warming. The following table present: the average amounts (in metric tons) of CG; emissions for the years 199?201 3 per person in the United States and per person in the rest of the world. 2002 3.3 19.6 2003 3.5 19.4 2004 3.7 19.6 2005 3.8 19.5 2006 3.7 19.0 2007 4.7 19.2 2008 4.7 18.5 2009 4.6 17.2 2010 4.6 17.5 2011 5.0 17.0 2012 5.0 16.3 2013 5.0 16.4a. Compute the least-squares regression line for predicting U.S. emissions from non-U.S. emissions. c. Predict the U.S. emissions for a year when the non-U.S. emissions level is 3.4
