Question

(LR-4) State the slope of the line of best fit. Carefully Interpret the meaning of the slope in a sentence or two.

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

I am writting y(cap) as y' here to type quickly.

Slope of line L : y = c + mx is m

This indicates, the change in y value on unit change in x.

y' = -4,443,755.85+244,351.32x

slope of the line is : 244,351.32

Here slope indicates "if the pass completion % for top [aid NFL quarterback increases by 1, then the predicted salary of top paid NFL quarterback would increase by $244,351.32
