Problem 3-9 (Algo) 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 2 3 4 5 275 New Accounts Period 200 6 211 7 211 8 223 9 235 10 New Accounts 231 249 250 258 267 Period New Accounts 11 281 12 13 281 14 288 15 316 Y 6.921 196.30 307.94 = Y16 Y17 = 313.96 Y18 = 320.88 Y19 327.80 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 (Tt) for Period 5 as follows: (Period 4 data Period 1 data)/3. Then compute the initial trend- adjusted forecast (TAFt) 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
