Create a bagging ensemble classification tree model using the accompanying data set (predictor variables: x₁ to x₄; target: y).

a. What are the overall accuracy rate, sensitivity, and specificity of the model on the validation data?

b. What is the AUC value of the model?

c. Score a new record with the following values: x₁ = 3.45, x₂ = 1, x₃ = 18, x₄ = 5.80. How would the record be classified using the bagging ensemble tree model? What is the probability of the record belonging to Class 1?
