An analyst must decide between two different forecasting techniques for weekly sales of roller blades: a linear trend equation and the naive approach. The linear trend equation is Ft = 123 + 1.8t, and it was developed using data from periods 1 through 10. Based on data for periods 11 through 20 as shown in the table, which of these two methods has the greater accuracy if MAD and MSE are used? (Round your intermediate calculations and final answers to...

1. Beyond Tea Inc. wants to forecast sales of its menthol green
tea. The company is considering either using a simple mean or a
three-period moving average to forecast monthly sales. Given sales
data for the past 10 months use both forecasting methods to
forecast periods 7 to 10 and then evaluate each. Which method
should they use? Use the selected method to make a forecast for
month 11. (Show all calculations .... Please read Examples1, 2, 3...
