(Round your intermedlate calculations and final answers to 2 decimal places.) Click here for the Excel Data Flle Answer is complete and correct. b. Use trend-adjusted smoothing with =0.3 and =0.2 to smooth the new account data in part a. What is the forecast for perlod 16 ? Compute the initial trend estimate (Tt ) for Perlod 5 as follows: (Perlod 4 data - Perlod 1 data) / 3 . Then compute the Initlal trendadjusted forecast (TAFt) for Period 5 as follows: Perlod 4 data + Initlal trend estimate for Perlod 5. Then compute all remalning 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 Intermedlate calculations. Round your final answer to 2 decimal places.) Answer is complete but not entirely correct
