Hair dryers have sold 100, 110, 120, and 130 units at Walgreens stores in Youngstown, Ohio, during the last four months ( with 130 being the mostrecent sales).Using these three strategies, build a moving-average forecast for next month:a) The three-month moving averageb) Moving average every four months.c) Weighted 4-month moving average, with the most recent month weighted4, the month before 3, then 2, and the month before that weighted 1, and the month before that weighted 1.d) Using a 4-month rolling average, predict the next month's sales (months) ifnext month's sales are 140 units.
The forecasting sales of Month 1 (F1) was 27, and the actual sale of Month 1 (A1) turned out to be 23 Using Exponential Smoothing method (Desired Respond Rate (Alpha) = 0.3), The forecasting sales of Month 2 (F2) is: ________ (Round your answer to the nearest integer)
Choose the type of forecasting technique (survey, Delphi, averaging, seasonal, naive, trend, orassociative) that would be most appropriate for predicting:d. The impact a price increase of 10 percent would have on sales of orange marmalade.
