Problem 10-11 (LO 10-3, 10-4)

A grocery store sells the following number of frozen turkeys during the week prior to Thanksgiving:

Using exponential smoothing, prepare a forecast of sales for each day, starting with F₁ = 85 and = 0.2. Compute the MAD and the tracking signal in each period. Use MAD₀ = 0. (Round all answers to 2 decimal places.)

Recompute part a using = 0.1, 0.3, and 0.4.
