A manager at a gas station realized that there
appeared to be a quadratic relationship between the
price he charged for a doughnut and the number he

What is the coefficient of determination (r2) for the
following data set using a quadratic model?
Prics charged for
a Doughnuts
$0.75
$0.99
51.10
$1.50
