Tuition Fees: The following table shows the average annual tuition and fees at private and public 4-year colleges and universities for the school years 2009-2010 through 2014-2015. Year Private Public 2009-2010 31,448 15,014 2010-2011 32,617 15,918 2011-2012 33,674 16,805 2012-2013 35,074 17,474 2013-2014 36,193 18,372 2014-2015 37,385 19,203 Using 1 for 2009-2010, 2 for 2010-2011, and so on, find the linear correlation coefficient and the equation of the least-squares line for the tuition and fees at private 4-year colleges and universities, based on the year. Using 1 for 2009-2010, 2 for 2010-2011, and so on, find the linear correlation coefficient and the equation of the least-squares line for the tuition and fees at public 4-year colleges and universities, based on the year. Based on the linear correlation coefficients you found in parts a and b, are theequations you wrote in parts a and b good models of the growth in tuition and fees at 4-year colleges and universities?
