The question is in the diagram below:

Say we want a model that will help explain the relationship between a student's exam grade and their attendance. Below are two defined variables, a regression equation and two example data points. Variables: Grd = Exam grade in % Abs = Number of absences during semester Regression Equation: Gro'" = 85.3 - 5.4*Abs Two example data points (observations): A student that was absent 5 times and got 70% on the exam A student that was absent 9 times and got 42% on the exam (a) Find the predicted value of exam grade (6rd\") for the student that was absent 5 times to 1 decimal place. Predicted exam grade for the student that was absent 5 times = % ('Idp) (b) The student that was absent 9 times would have a predicted exam grade of 36.7%. What is the residual for this observation to 1 decimal place? Residual for student that was absent 9 times = % (1dp)
