Thirteen students entered the undergraduate business program at Longstreet College two years ago. The table near the top of the next column indicates what their GPAs were after they were in the program for two years and what each student scored on the SAT math exam when he or she was in high school.
(a) Is there a meaningful relationship between GPAs and SAT math scores? Justify your answer.
(b) If Gwen gets a 490 SAT math score, what is her predicted GPA?
(c) If Jarvis gets a perfect 800 SAT math score, what is his predicted GPA? Is it appropriate to use this model to predict Jarvis’s score? Why or why not?
