1. The manager of a large public library must schedule employees to re-shelve books and periodicals checked out of the library. The number of items checked out will determine the labor requirements and whether additional shelf storage space is needed. The number of items checked out of the library over the past two years is as follows: Veat Minek fismand Deccentier \&3UU a. Find the single exponential smoothing forecast for January of 2022 using both MDLDDDand[DDDDDDDInitiate the models with forecast of 2045 for January of 2020 . Your Spreadshect should be able to recompute the forecasts by simply changing the value of a in a cell. bDDUsing MAE (bias), MAPE, and MAD, whichDD is better? Again, MAE, MAPE, and MAD should recompute once DJis changed] c. Do you think single exponential smoothing is a suitable choice to be used with the above data? Explain your answer. 2. For the demand data below, use time series decomposition to make a forecast for the four quarters of 2022 . Use the multiplicative model
