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 periods 16 through 19. (Round your intermediate calculations and final answers to 2 decimal places.) Click here for the Excel Data File b. Use trend-adjusted smoothing with =0.3 and =0.2 to smooth thje new account data in 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 data) / 3. Then compute the initial trendadjusted forecast (TAF) for Period 5 as follows: Period 4 data + Initial trend estimate 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 dect-rat places and other values to 2 decimal places for intermediate calculations. Round your final answer to 2 decimal places.)
