Questiоn 5 Predictiоn (8 pоints) 5а) (3 points) Using testDаtа, use the following models to predict the life expectancy : i) model 2 ii) model 3 iii) model 4 Show the first five predictions using each model along with their true values. 5b) (2 points) Compare the predictions using mean squared prediction error and the precision measure. Which model performs the best? 5c) (3 points) Using the first row of testData, predict the life expectancy using model2 (full model). What is the 99% prediction interval (PI)? Provide an interpretation of your results.
