Kindly pls showing me how to solve this using the Microsoft Excel!!!

2. (25 points) Monthly demand at A\&D Electronics for flat-screen TVs are as shown in the following table. Estimate demand for the next two months using (a) simple exponential smoothing with =0.3 (b) and Holt's model with =0.05 and =0.1. For the simple exponential smoothing model, use the level at Period 0 to be L0=1,659 ( the average demand over the 12 months). For Holt's model, use level at period 0 to be L0=948 and the trend in Period 0 to be T0=109 (both are obtained through regression). Evaluate the MAD, MAPE, MSE, bias, and TS in each case. Which of the two methods do you prefer? Why
