A linear regression model is constructed to predict student GPA percentile (on a 0-100 scale) from their SAT-Math score. You are to make the relevant prediction for a student who has a SAT-Math score of 600 (note that SAT scores go from 200 to 800). Based on the following regression output, what is the expected percentile of his GPA? Coefficient T-statistic Intercept 20 0.3 SAT-Math 0.1 5.0 R-squared = 0.36 O A. 60th percentile O B. 10th percentile O C. 20th percentile O D. 80th percentile
