Table 1: Quarterly demand information over past four years.
You were assigned to conduct this supplier selection exercise. In order to carry out this
exercise, you managed to collect quite a lot of data. You first managed to collect the
demand history, on a quarterly basis, over the past four years. The demand data is shown
in Table 1. Based on the observation of the demand, you decided to use a static time series
model to estimate the level, trend and seasonality

You are supposed "to estimate the level, trend, and seasonality" of what?

You've been told that "you decided to use" a particular type of regression model. If your class hasn't yet covered how to do this, then try online lessons, such as this. ;)
