Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer.
the equation of the regression is :
y^ = .17+.54*x1+.002*x2
GPA = 3.2
College board score = 400
We will substitute x1 = 3.2 and x2 = 400 in the equation . we
have:
y^ = .17+.54*3.2+.002*400
= 2.6980
The predicted college GPA for a high school GPA of 3.2 and a college board score of 400 is 2.6980

An achievement test given to high school seniors is used to predict college GPA. The following relationship between the test scores and college GPA exists within the entire population of students: 1. Y 0.10+3.94 X+ E In the above, Y (response) is the college GPA of a given student, X is the student's score on the achievement test (predictor, scored as proportion correct, between 0 and 1), and e is random error, with E~N(0,.005), where the value.005 is the variance...

A dean of a business school has fit a regression model to predict college GPA based on a student's SAT 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 SUMMARY OUTPUT Regression...
