Please help. For the first part, I believe using a trend projection with regression using a simple regression analysis can help forecast.= for this model where y= a period's demand and t=time period. Is this forecast method correct? I do not have forecasting software and the demand is shown by a time series data.

Thank you

Briefly answer the following questions. 1. (Chapter 8) The demand for an item over the last year is plotted below. Develop a forecast and explain why your approach is reasonable (8 points) Demand 120 100 80 60 Demand 40 20 0 1 2 3 4 5 6 7 8 9 10 11 12 2. (Chapter 8) What are the steps of the forecasting process as described in the text (6points)
