The data are shown below and are available in the excel file exercise 5.xls. $ Based on the standard model, the estimate of the residual standard deviation is = 0133 . . The table of treatment averages is shown below. Is there any evidence of differences among the treatments? Is there any evidence of interaction? Prepare an interaction plot. Use the interaction plot to argue that the new design is less sensitive to changes in environmental conditions (temperature and humidity). What limitations apply to this argument?
