True and false:

2. [5 marks] A linear regression model is fit to model the linear relationship between the response variate (y) and the explanatory variate (x). Some plots have been constructed in order to check the validity of the model: Scatterplot of Data Residual vs x 40 60 0 20 Standardized Residual o 0 8 O 500 -2 o 10 15 20 15 20 Qqplot of Residuals Sample Quantiles 2 3 -3 -2 -1 0 Theoretical Quantiles Here is some related R output that you may use to answer the questions below: -8. 4792 2. 4708 t value Pr (>It/) (Intercept) Estimate Std.
