could you answer this in an excel file. It is hard to understand with every step typed out instead of being in excel.

Consider quarterly demand for washing machines developed by the South Dakota-based Superior Washing Corporation, as shown in Table 2. After obtaining initial estimates for level, trend, and seasonal factors, forecast quarterly demand for year 5 using Winter's model with alpha =0.2, beta =0.2 and gamma =0.2. Evaluate the MAD, MAPE, MSE, bias, and TS for the forecast. Table 2 Ouarterlv Demand for Washing Machines Please also do the following as part of your detailed solution: 1. Please describe in detail how you mathematically implemented the procedure of Winter's model in order to determine the forecasts for Period 5 . 2. Show your calculations on Microsoft Excel. Dedicate one spreadsheet for each method. 3. Label the cells on your spreadsheet clearly. 4. Present your data in the form of a line chart with "Periods" on the x-axis and "Demand" on the y-axis
