Just need help with b. A is all correct

a. Obtain the linear trend equation for the following data on new checking accounts at Fair Savings Bank and use it to predict expected new checking accounts for perlods 16 through 19. (Round your intermedlate calculations and final answers to 2 decimal places.) b. Use trend-adjusted smoothing with =.2 and =1 to smooth the new account data in part a. What is the forecast for period 16 ? Compute the initial trend estimate (Tt) for Perlod 5 as follows: (Perlod 4 data - Perlod 1 data) / 3 . Then compute the Initial trendadjusted forecast (TAFt) for Perlod 5 as follows: Perlod 4 data + Inltial 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 (Tt) to 3 decimal places and all other Intermedlate forecast values (TAFt and St) to 2 decimal places. Round your final answer to 2 decimal places.)
