Question 1163704: The data in the chart show the cost of tuition at a state university for the years 1997-2001. Fit a regression line to the data, where x is the number of years after 1997. Then find the coefficient of correlation. Finally, use the regression line to predict the cost of tuition in 2006, 2009, and 2012 .
Year X tuition Y
0. 1997 9753
1. 1998 10,199
2. 1999 10,970
3. 2000 11,533
4. 2001 12,049

letting 0=1997,
y=592.6x+9123
r^2=0.994
r, the coefficient of correlation, is 0.997
in 2006, x=9 so tuition is 592.6*9+9123=$14,456
2009, x=12 so $16,234
2012 x=15 so $18,012
