A teacher has modelled students' grades based on the number of hours of independent study throughout the semester. She has used linear regression analysis- and found out that the grade can be modelled by: Y = 3.15 r + 18.5 a. Interpret the value 18.5 in this case/scenario (2.5 points) b. Interpret the value 3.15 in this case scenario (2.5 points). Predict a grade for a student who has studied 12 hours. (2.5 points) d. What are this model's limits? (2.5 points) 10 minutes on slide
