Question

(LR-3) Find the line of best fit (regression line) and graph it on the scatter plot. State the equation of the line.

Group Member #1 (Activity Sheet 1) Sample Regression Equation: y--4,443,755.85+244,35132x ý predicted salary of 2009-2010 top paid NFL quarterback in $ x-pass completion % for top paid NFL quarterback in 2009-10 It is important that students use ý instead of y for the response variable and define it to be the predicted salary of a 2009-2010 top paid NFL quarterback in S. Correlation r: r=0.3940 Coefficient of Determination : -0.1553 Scatterplot with Least-Squares Regression Line: 225000000 20000000 15000000 r, 10000000 N5000000 0 10 20 30 40 50 60 70 80 tion % for 30 Highest Paid NFL Quarterbacks in 2009-2010 It is important that students label the two axes, clearly indicating the explanatory variable on the horizontal axis and the response variable on the vertical axis.

Explanation / Answer

The answer is given itself on the image and since the data is not mentioned it is not possible to verify whether there is any other better regression line than this. So, regression line is,

Y ( predicted y ) = -4443755.85 + 244351.32*x
