Discuss the scenarios in which each model would be most appropriate.

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 semesterRegression Equation:Grd^ = 85.3 - 5.4*AbsTwo example data points (observations):A student that was absent 5 times and got 70% on the examA student that was absent 9 times and got 42% on the exam(a) Find the predicted value of exam grade (Grd^) for the student that was absent 5 times to 1 decimal place.Predicted exam grade for the student that was absent 5 times = Answer 1 Question 5 % (1dp)(b) The student observation above, that was absent 9 times and got 42% on the exam, 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 = Answer 2 Question 5% (1dp)(c) Interpret the slope in context. Answer 3 Question 5(d) Interpret the intercept in context. Answer 4 Question 5.(e) Is the interpretation of the intercept meaningful in context? Answer 5 Question 5
