The table below shows semi-annual demand (in thousands) for Didgets (they're like Widgets, only they're easier to work). A linear trend has been estimated using this data set with t = 1 for 1991.1 and t = 6 for 1993.2. It has an intercept of 1.66 and a slope of 0.24. Use the ratio-to-trend method to calculate seasonal adjustment factors for the first and second half of the year and then forecast the level of demand for 1996.1 and 1996.2. Note: Round all intermediate calculations to two decimal places.
$$\begin{array} { l c }
\text { Year } & \text { Demand } \
1991.1 & 1.8 \
1991.2 & 2.4 \
1992.1 & 2.2 \
1992.2 & 2.8 \
1993.1 & 2.5 \
1993.2 & 3.3
\end{array}$$
