Consider the following estimated trend models. Use them to make a forecast for t= 22. a. Linear Trend: ý = 12.42 + 1.13t (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) b. Quadratic Trend: û = 18.04 + 1.04t - 0.02t2 (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) c. Exponential Trend: In(y) = 1.6 + 0.08t, se = 0.01 (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
