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.) Period Y 2 12345 Y16 Y17 Y18 Y19 New Accounts Period New Accounts 200 214 211 228 6189 232 Period 11 New Accounts 281 7 248 12 275 250 13 280 253 14 288 235 10 267 15 310 t b. Use trend-adjusted smoothing with a = .3 and ẞ = .2 to smooth the new account data in part a. What is the forecast for period 16? Compute the initial trend estimate (T+) for Period 5 as follows: (Period 4 data - Period 1 data) / 3. Then compute the initial trend-adjusted 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. (Use 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.) Forecast for period 16
