Provide the equation of the linear regression line (3
pts):
Provide the coefficient of correlation (2 pts):
How many would free throws would you expect a 42 year old to make
(2 pts):
What is the residual for the 42 year old we sampled (2 pts):
The statistical software output for this problem is :
The equation of the linear regression line is : y = 31.974 - 0.260 X
coefficient of correlation = -0.41
Free throws = 21.06
Residual = 25 - 21.06 = 3.96
