1.3. If the coefficient of multiple determination is as follows explain what it measures. 1.4. The following 95 % confidence intervals were then obtained for ₁ and ₂ B₁: (5≤B₁ ≤6) B₂: (-2≤B₂ ≤ -0.5) Interpret both intervals. 1.5. Is the predictor variable AGE contributing in the explaining of the variation in scrap metal waste? Show how you can answer this question if the standard deviation of AGE is 0.6223 years. 1.6. The regression is run again on the dataset but the predictor AGE is taken out. Can we use the model given by SAS but with AGE taken out? Motivate your answer.
