3. Agraduate school committee is studying the relationship between x, an applicants' undergraduate grade point average and y, the applicants' score on the graduate entrance exam. The following random sample was collected to study this relationship. | x (GPA) 3.2 | 3.9 | 4.0 | 3.4 | 3.7 3.0 y (score) 725 788 775 647 800 672 Refer to your EXCEL Homework for the calculations. a. Write a sentence interpreting the value of the slope of the regression line. b. Give a brief explanation of the meaning of the coefficient of determination in the context of this problem. c. If a student has a grade point average of 3.4 what does the least-squares line predict for the score on the graduate entrance exam? Is this interpolation or extrapolation? d. What does the correlation coefficient tell us about the relationship between GPA and graduate entrance exam score? (Include a statement about direction, form, and strength.)
