Problem 3.9 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 1 New Accounts 230 New Accounts 200 216 211 229 235 WN Period 6 7 8 9 10 New Accounts 281 275 246 Period 11 12 13 14 15 250 257 267 4 5 286 288 317 Y16 = Y17 = 728 = 719 = 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 (Te) for Period 5 as follows: (Period 4 data - Period 1 data)/3. Then compute the initial trend adjusted forecast (TAF d) for Period 5 as follows: Period 4 dataInitial trend estimate for Period 5. Then compute all remaining values (including the St value for Period 5) using the textbook formules or Excel template (Round the "Trend values (Tt) to 3 decimal places and all other intermediate forecast values (TAPt and St) to 2 decimal places. Round your final answer to 2 decimal places.) Forecast for period 16
