Use trend-adjusted smoothing with =0.3 and =0.2 to smooth the new account data part a. What is the forecast for period 16 ? Compute the initial trend estimate (Tt) for Period 5 as follows: (Period 4 data - Period 1 dato) /3. Then compute the initial trendadjusted forecast (TAF,) for Period 5 as follows. Period 4 data + Initial trend estumate for Period 5 . Then compute all remaining values (including the St value for Period 5) using the textbook formulas or Excel template. (Round the "Trend" values to 3 decimal places and other values to 2 decimal places for intermediate calculations. Round your final answer to 2 decimal places.)
