Predicting on test data

Now that you've trained the model on the train set, let's apply the model to the test data, make predictions, and evaluate the predictions. Recall that having a separate test set here simulates the gathering of a "new" independent dataset to test our model's predictive performance on.

The datasets train and test, and the trained model, train_model_2 are available in your workspace.
