Question: Open the US Life Expectancy Data. Fit the Trend and Lag 1 models for Overall Life Expectancy. Copy and paste the regression statistics and coefficients

Open the US Life Expectancy Data.
Fit the Trend and Lag 1 models for Overall Life Expectancy. Copy and paste the regression statistics and coefficients tables for each model into your paper.
Which of the two models makes the better predictions? What do you base your answer on?
Give the 2020 predictions for each model.
Additional Extra Credit: Assume the 2020 prediction from the Trend model gives the actual value of overall life expectancy for 2020. Add this value to the dataset. Then, with this additional data point, fit new Trend and Lag 1 models for Overall Life Expectancy.

Which of these two new models makes better predictions?
Give the 2030 predictions for each of these new models.
