The Excel file Closing Stock Prices provides data for four stocks and the Dow Jones Industrial Average over a one-month period.

3. Develop a spreadsheet for forecasting each of the stock prices and the DJIA using a simple two-period and three-period moving average.

4. Compute MAD, MSE, and MAPE and determine whether two or three moving average periods is better.

PROBLEM #3 (10 marks): Problem #9 in Ch. 9 on page 353 using the Excel file ‘ClosingStockPrices’. Don’t do #9b. For #9c, compute and compare MAD and MSE only.
