Question:
College students were asked how many classes they failed to attend in the past 3 weeks as well as their current grade point average. We obtained the following regression equation from the resulting data: GPA = 3.49 − 0.07(number of skipped classes). What does the slope of the regression line mean in context?
A. As the predicted GPA increases by one, the number of classes skipped goes down by 0.07.
B. As the predicted GPA increases by one, the number of classes skipped goes down 0.07 times.
C. For every additional class skipped, the GPA is predicted to go down 0.07 points.
D. For every class skipped, the GPA will go down by 0.07 times.
