Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the jwt-auth domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

Question 2: Statistical Significance – 4 points a. 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. Using model2, interpret the coefficient of bp in the context of the data description. State any assumptions while interpreting the coefficient. (2 points) b. 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)
