Determine the seasonally adjusted forecast for each of the tour quarters of the sixn year. 12. Team Sports, Inc., sells sporting goods to high schools and colleges via a nationally dis- tributed catalog. Management at Team Sports estimates it will sell 2,000 Wilson Model A2000 catcher's mitts next year. The deseasonalized sales are projected to be the same for each of the four quarters next year. The seasonal factor for the second quarter is 145. Determine the seasonally adjusted sales for the second quarter of next year. 13. Refer to Exercise 9, regarding the absences at Anderson Belts, Inc. Use the seasonal indexes you computed to determine the deseasonalized absences. Determine the linear trend equation based on the quarterly data for the three years. Forecast the seasonally adjusted absences for 2009 14. Refer to Exercise 10, regarding sales at Appliance Center. Use the seasonal indexes youExplanation / Answer
Total number of sales in the year=2000.From time series properties,we know that deseasonal data=actual data-seasonal factor and also the sum of seasonal factors in a year is zero.So,sum of deseasonalised sales in 4 quarters will be equal to toal sales in the year=2000.So,deseasonal sales in each quarter is = 2000/4=500.Now,for second quarter the seasonality factor is 145.So, according to time series,seasonally adjusted sale=deseasonalised sale+seasonal factor=500+145=645.We have used the same logic as of the first line.
