3. Check all four assumptions for this model. For each assumption indicate which graph is used to check this assumption (Example: normal quantile plot, residual plot). Also indicate whether the assumption has been met. Finally, provide an explanation for why the assumption is met or not met. For multiple regression we check the same set of assumptions as in simple linear regression. (Hint: To create these plots we must first save the residuals and the predicted values from the multiple regression model. ) (i) Independence: Graph used to check assumption: Is the assumption met? Provide explanation: (ii) Form of the model: Graph used to check assumption: Is the assumption met? Provide explanation: (iii) Constant Variance: Graph used to check assumption: Is the assumption met? Provide explanation: (iv) Normality: Graph: Graph used to check assumption: Is the assumption met? Provide explanation
