Questiоn 2: Stаtisticаl Significаnce - 6 pоints Fоr this question, use the trainData. In model1, which regression coefficients are significant at the 95% confidence level? Are these the exact same regression coefficients that are significant at the 90% confidence level? (2 points) Using the unstandardized data (trainData), build a new model using only the variables whose coefficients were found to be statistically significant at the 95% confidence level. Call it model2. Display the model summary. Interpret the coefficient of bp in the context of the problem. State any assumptions while interpreting the coefficient. (2 points) Perform a Partial F-test to compare the reduced model(model2) with the full model (model1) and interpret it at the 95% confidence level. Which one would you prefer? Is it good practice to select variables based on the statistical significance of individual coefficients? Why or why not? (2 points)
