I want from exercise 1 Point (1): to see the comments on the trend, the shape of the graph if they are ok or I need to put something else. Point (2): I did the regression analysis. I want only to see my comments if they are ok or it needs to put something extra. Point (5): I want only the comment on how valid this estimate is likely to be. Point 6: I did the regression analysis and I wrote some comments but I am not sure if I answer the comment that wants to give on its validity. I want from exercise 2 Part1_Point (2): to see my reasons whether I think a multiplicative or additive model is likely to be better here. Part1_Point (5): wants a column showing the residuals from your model? How I find the residuals? Tell me only what to do and I will put in the excel file. I think that residuals = Adjusted Seasonal Variations – Seasonal Variations ( not sure!!) Part2_Point (2): see my comments about the trend and fitted model if they are ok. Part2_Point(3): I want help how to compare the residuals from excel with that from the minitab model.
