Graduate student enrollment. A linear regression model for the graduate student enrollment in Table 8 is

y = 0.033x + 1.27

where x represents years since 1980 and y is graduate enrollment in millions of students.

(A) Draw a scatter plot of the graduate enrollment data and a graph of the model on the same axes.

(B) Predict the graduate student enrollment in 2016 (to the nearest 100,000).

(C) Interpret the slope of the model.
