Final and course grade: For this data set, the least squares regression line is Y = 31.72 + 0.62X, where X represents the final exam score as a percent and Y represents the predicted course grade as a percent. A student who earns a 45% on the final exam is predicted to earn a course grade of 32%. Which one of the following is a reason the prediction is not accurate?  There is a calculation error.  There are no students in the data set who earned 45% on the final exam.  This is considered an extrapolation.
