For Analytic Solver, partition data sets into 60% training and 40% validation and use 12345 as the default random seed. Create 10 weak learners when constructing the ensemble model. If the predictor variable values are in the character format, then treat the predictor variable as a categorical variable. Otherwise, treat the predictor variable as a numerical variable.

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