Forecasting and Demand Management process in a mining industry

forgiven product demand the time series trying equation is 53.3+2.1 X what is your forecast demand for period six?

Week 1 2 4 Forecast Method 1 0.90 1.05 0.97 1.22 Actual Demand 0.72 1.05 1.00 0.97 Week 1 2 3 4 Forecast Method 2 0.82 1.19 0.90 1.17 Actual Demand 0.72 1.05 1.00 0.97 0 The MAD for Method 1 = thousand gallons (round your response to three decimal places). The mean squared error (MSE) for Method 1 = thousand gallons (round your response to three decimal places). The MAD for Method 2 = thousand gallons (round your response to three decimal places). The mean squared error (MSE) for Method 2 = thousand gallons (round your response to three decimal places).
