Preparing the dataSet Area Code & Churn to String via TransformationTab2 Nodes Used Model Training2 Nodes Used Model Evaluation1 Node UsedAccuracy = 93% Challenge 23: Modeling Churn Predictions - Part 1Description: A telecom company wants you to predict which customers are going to churn (that is, are going to cancel their contracts) based onattributes of their accounts. To this end, you are expected to use a decision tree classifier. The company gives you two datasets (training and test),both with many attributes and the class ‘Churn’ to be predicted (value 0 corresponds to customers that do not churn, and 1 corresponds to thosewho do). You should train the decision tree classifier with the training data, and assess its quality over the test data (calculate the accuracy,precision, recall, and confusion matrix for example).Note 1: This challenge is a simple introduction to predictive problems, focusing on classification. You are expected to just apply a decision treeclassifier (and get an accuracy of about 92%). A simple solution should consist of 5 nodes. DONENote 2: In this challenge, do not change the statistical distribution of any attribute or class in the datasets, and use all available attributes.
