Work on problem 4 (a forecasting problem) in textbook p. 70. Answer parts a-e. You could either use a calculator or Excel. (I prefer if doing this question by calculator and show me the formulas so it will help me for understating better)
*I have attached a PDF and a PowerPoint for questions 1 (page70 and the PowerPoint) please look at it.
