In this discussion, we will look back at the work we have done with Fred in previous R assignments. For this discussion, you will work with Fred's baseline data and his intervention data. Use the data set that contains both Fred's baseline and intervention data. Looking at both variables, test for trending and autocorrelation in both phases. What are the results? Based on the results, what test(s) of statistical significance could you use to compare the phases? Please provide all the information necessary to justify your position
