Consider the following estimated trend models. Use them to make a forecast for y at t = 24. a. Linear Trend: yˆ = 11.78 + 1.16t (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) b. Quadratic Trend: yˆ = 19.17 + 0.94t − 0.03t2 (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) c. Exponential Trend: ln(y)ˆ = 1.2 + 0.07t; se = 0.02 (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
