    4*$6‚377.185= $25‚508.74 every 4 years. (LR-5) Values of r2 and r: From the above line of best fit‚ we can see that the coefficient of determination r2= 0.9499. Since the slope of the regression line is positive r will be positive as well. Therefore the correlation coefficient r = √0.9499 = 0.97. We know that when r= 1‚ the correlation is considered a perfect positive correlation‚ and since our r= 0.97‚ it indicates that the linear relationship is very strong because it is very close to 1. (LR-6)
