(a) Use technology to find the equation and coefficient of determination for each type of regression
model. Use the number of practice throws for the input variable and the number of free throws for the
output variable. Round all decimal values to three places.
(b) Using the Equation of Regression, predict how many free throws a player will make if they took 20
practice throws. Round all decimal values to three places.
(c) Using the Equation of Regression, predict how many practice throws a player took if they made 15
free throws. Round all decimal values to three places.
