Questiоn 2: Mоdel Building (17 pоints) For this question, use the trаinDаtа. (2ai) (2 points) Fit a logistic regression model using all of the predicting variables. Display the summary for the model. Call it model1. (2aii) (2 points) Using only the summary output for model1, is the model with all the predictors better at predicting the response than a model with just an intercept term? Explain your reasoning. 2b) (4 points) Give an interpretation of the coefficient of the following predictors with respect to both the log-odds and also the odds of preferring remote work. i) RemoteWorkHoursPerWeek ii) CompanySizesmall 2c) (4 points) Is the coefficient of "Salary" statistically significant at 0.01 significance level? i) State the Null and Alternative hypotheses. ii) State the sampling distribution that the test statistic follows and describe the approach of how to derive the statistical significance of the coefficient. 2d) (5 points) Decision tree model i) Fit/train a Decision Tree model, call it model2, and display the summary of the model. Note: Use metric = "Accuracy", trControl = trainControl(method="cv", number=3). ii) State the mean accuracy for the model.
