Using the accompanying Student Grades data, construct a scatter chart for m idterm versus final ex am grades, and add a linear trendline.

What is the model for the trendline?

Fi nal E xam

Grade= ? +?M idterm Grade

If a student scores 77 on the m idterm, what would you predict her grade on the f inal exa m to be?
