Questiоn 2: Multiple Regressiоn Mоdel (11 points) 2а) Using the dаtаset "diamonds", perform a multiple linear regression to predict the price using the predicting variables "cut" and "depth". Call it model1. Display the summary. i) What are the model parameters and their estimates? ii) Interpret the coefficient for the "depth" predictor in the context of the problem. (4 points) 2b) Create a full linear regression model using all the predictors in the dataset. Call it model2. Display the summary. i) Interpret the coefficient corresponding to cutPremium in the context of the problem. (3 points) 2c) Compare model1 and model2 using a partial F-test using an alpha level of 0.01? State the null and alternative hypothesis. Describe how the test statistic is derived. State your conclusion based on this test. (4 points)
