###### Question:

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 New Accounts Period New Accounts Period New Accounts 200 239 11 281 275 2 213 7 246 12 3 211 250 13 287 260 267 224 14 288 5 235 10 15 315 Y 6.95 196.2 t Y16 307.32 Y17 = Y18 Y19 314.27 321.21 328.16 NmstL
b. Use trend-adjusted smoothing with a 2 and B 1 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. (Round the "Trend"values (Tt) to 3 decimal places and all other intermediate forecast values (TAFt and St) to 2 decimal places. Round your final answer to 2 decimal places.) Forecast for period 313.16 16
