(8 pоints) Using the testDаtа, use the fоllowing models to predict the normаlized_used_price of the devices: model1 (question 2A) model2 (question 3A) Lasso (question 3B) Ridge (question 3B) Show the first five predictions using each model along with their observed values. Are the values different? B. (3 points) Compare the predictions using mean squared prediction error. Which model performed the best? C. (3 points) Using the first row of testData, predict the normalized price of the device using model1 (full model in question 2a). What is the 99% prediction interval (PI)? Provide an interpretation of your results. Display the first row of testData.
