i need asap answers plz

1. Given the data below, compute for the following: a) Forecasts for P5 to P12 using a 4-period simple moving average b) Forecasts for P5 to P12 using a 4-month weighted moving average with the following weights: Most recent period = 0.40 2nd most recent period = 0.30 3rd most recent period = 0.20 4th most recent period = 0.10 Assuming a forecast of 5,000 units for Period 4 and a = 0.30, compute for the forecasts for P5 to P12. d) Using linear trend forecasting, determine the: - equation of the linear trend line - compute for the forecast for P5 to P12.
