You are given the demand and forecast history for Apple iPhone 12. According to this, what is the 3-period weighted moving average forecast for Week 11 with weights 1,2,3? (Use the first weight for the oldest (the least relevant) demand value. Do not round intermediate calculations. Round your final answers to two decimal places. Hint: If weights do not add up to 1, they need to be normalized with the sum of the weights, which is 6 in this case. For example: weight 1 becomes -0.167(@orsdemir, Copyrighted content.
