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 calculotions and final answers to 2 de places.) Period 1 2 3 4 5 New Accounts 200 217 211 225 235 New Accounts 231 249 Period 6 7 8 9 10 Period 11 22 13 14 15 250 New Accounts 281 275 283 288 301 252 267 Y Y16 717 Y18 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 (T) for Period 5 as follows: (Period 4 data - Period 1 data)/3 Then compute the initial trend- adjusted forecast (AF) for Perlod 5 as follows: Period 4 data + Initial trend estimate for periods. Then compute all remaining value including the S, value for Period 5) using the textbook formulas or Excel template (Round the "Trend"Values (Tt) to 3 decimal plac and all other intermediate forecast volues (TAFt and St) to 2 decimal places. Round your final answer to 2 decimal places.) Forecast for periods
