Q 4. (A) The Accuweather Corporation manufactures barometers and thermometers for weather forecasters. In an attempt to forecast its future needs for mercury, Accuweather's chief economist estimated average monthly mercury needs as: N = 500 + 10X where N = monthly mercury needs (units) and X = time period in months (January 2008= 0). The following monthly seasonal adjustment factors have been estimated using data from the past five years: Month January April July September| December |Adjustment Factor 15% 10% 120% 5% 010% |(a) Forecast Accuweather's mercury needs for January, April, July, September, and December of 2010. |(b) The following actual and forecast values of mercury needs in the month of November have been recorded: Year Actual Forecast 2008 456 480 2009 324 360 2007 240 240

Hi, I need help with solving for the following values (boxed). Thank you.
The number of cases of merlot wine sold by the Connor Owen winery in an eight-year period is as follows: CASES OF MERLOT WINE 276 362 YEAR 2005 2006 2007 2008 2009 2010 2011 2012 404 462 364 506 416 382 Using an exponential smoothing model with an alpha value of 0.30, estimate the smoothed value calculated as of the end of 2012. Use the average demand for 2005 through 2007 as your initial forecast for 2008, and then smooth the forecast forward to 2012. (Round your intermediate calculations and final answer to the nearest whole number.) Answer is complete but not entirely correct. Forecast for 2012 372
