Read Problem 6 inChapter 6 of your textbook. Calculate and answer parts a through d. Include allcalculations and spreadsheets in your post. Explain why the moving averagemethod was used instead of another forecasting method. What might be anotherforecasting method that could prove to be just as useful? Your initial post shouldbe 200-250 words. The figures below indicate the number ofmergers that took place in the savings and loan industry over a 12-year period.                                                           Year    Mergers    Year    Mergers    2000    46    2006    83    2001    46    2007    123    2002    62    2008    97    2003    45    2009    186    2004    64    2010    225    2005    61    2011    240   a. Calculate a 5-year moving average to forecastthe number of mergers for 2012. b. Use the moving average technique to determinethe forecast for 2005 to 2011. Calculate measurement error using MSE and MAD. c. Calculate a 5-year weighted moving average toforecast the number of mergers for 2012. Use weights of 0.10, 0.15, 0.20, 0.25,and 0.30, with the most recent year weighted being the largest. d. Use regression analysis to forecast thenumber of mergers in 2012. 2. Find the exponentially smoothed series forthe series in Problem 6, (a) using A = 0.1 and then (b) using A =0.7, and plot these time series along with the actual data to see the impact ofthe smoothing constant.
