Using the PewShop dataset, we have found that age affects your score on the Technology Index: the older you are, the less technology you have. But is this relationship linear or nonlinear? Run a set of regression models, the fi rst one with the regular age variable, and the second with the regular age variable and the square of this variable. Create a table that includes both models; then create a graph and explain your results.
