On your own = Create a model that predicts audience_rating using a cubic curve (polynomial with degree 3), and assign this model to movie_cubic. = Create a scatterplot with audience_rating on the y-axis and critics_rating on the x-axis using your test data. = Using the names of the three models you have trained, add the line of best fit, best fitting quadratic curve, and best fitting cubic curve for the training data to the plot. = Based on the plot, which model do you think is the best at predicting the test data? = Use the test MSE to verify which model is the best at predicting the test data.
