I perfоrmed а lineаr regressiоn exercise оn а dataset. The model summary on the training partition appears below:   Coefficients: Estimate Std. Error t value Pr(>|t|) (Intercept) 1.354e+04 6.447e+02 21.003 < 2e-16 *** Age_08_04 -1.428e+02 3.262e+00 -43.789 < 2e-16 *** KM -1.814e-02 1.779e-03 -10.194 < 2e-16 *** HP 5.420e+01 3.933e+00 13.780 < 2e-16 *** Fuel_TypeDiesel 2.669e+03 4.519e+02 5.907 4.78e-09 *** Fuel_TypePetrol 5.208e+02 4.264e+02 1.221 0.222 Sport_Model 5.443e+02 1.011e+02 5.386 8.99e-08 *** --- Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 Residual standard error: 1474 on 1000 degrees of freedom Multiple R-squared: 0.833, Adjusted R-squared: 0.832 F-statistic: 831.5 on 6 and 1000 DF, p-value: < 2.2e-16 The plot of fitted values and residuals appears below:   Answer the following questions based on the above summary and plot: What is the regression equation? (Fuel_type is a categorical attribute with values "CNG", "Diesel" and "Petrol. Sport_Model is 0 or 1) (3 points) From the regression output, how can you identify if a predictor is significant or not? What do you need to see if a coefficient is significant? (2 points) What is the RMS error on the training partition? (1 point) What does this RMS error say about the values that the model predicts on average? (2 points) What proportion of the variation in the target attribute does the model explain? (1 point) Does the model seem to have any non-linearity? Why do you say that? (2 points) If the model has nonlinearity, how can you address it? Write a sentence about what you would do. (2 points)
