This assignment requires you to prepare an R file or a Stata do -file (referred to as “analysis file” from now on) that contains all code answering the questions and an excel file. Write your interpretations of the analysis results and the answers to the questions as comments to the analysis file. Before submitting the analysis file, make sure that it is sufficiently commented and that it runs without errors from start to end.
