In past exercises, we’ve analyzed the effect of respondent’s education on concern about her job, finding that more educated people have less concern than less educated people. Could this relationship be nonlinear? Use the PewWork-Play dataset in order to run a set of nested regression models, using the “Concern about Job” index as your dependent variable. For your first model, use only the recoded education variable (XYeduc). For your second model, add the squared education variable. Build a professionallooking table, create a graph, and explain your results.
