LAB 2 Part 4

Exercise: Train a Decision Tree ModelThe provided metanode contains a workflow that accesses and preprocesses demographics, geo coordinates, andtravel risk information in different countries/territories. Specifically, it creates a binomial column Travel with twovalues "Travel safely" and "Travel with care" based on the travel risk categories. Your task is to predict this travel riskcategory via the following steps:1. Partition the data into a training set (70%) and a test set (30%). Apply stratified sampling on the Travel column.2. Build a decision tree model to predict the travel risk category (Travel column). Apply the model to the test set.3. Evaluate the model's performance.
