The director of graduate admissions at a large university is analyzing the relationship between scores on the math portion of the Graduate Record Examination (GRE) and subsequent performance in graduate school, as measured by a student’s grade point average (GPA). She uses a sample of 8 students who graduated within the past five years. The data are as follows:

a. Construct a scatter plot placing GRE on the horizontal axis.
b. Find the sample regression equation for the model:
GPA = β0 + β1 GRE + .
c. What is a student’s predicted GPA if he/she scored 710 on the math portion of theGRE?
