A dean of a business school has fit a regression model to predict college GPA based on a i on a student's SAI score (SAT_Score), the percentile at which the student graduated high school (HS_Percentile) (for instance, graduating 4th in a class of 500 implies that 496 other students are at or below that student, so the percentile is 496/500 x 100 = 99), and the total college hours the student has accumulated (Total_Hours). The regression results are shown below. What would be the estimated mean GPA for a student with an SAT score of 1120, a high school percentile rank of 84, and total accumulated hours of 33? In the calculation and answer, use three decimal places.
