solve B explanation

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 1 286 6 238 11 281 2 216 7 24-4 12 275 3 211 8 256 13 284 4 225 9 251 14 288 5 235 16 267 15 312 b.Use trend-adjusted smoothing with d = .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) I 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 and all other intermediate forecast values (TAFt and St] to 2 decimal places. Round your final answer to 2 decimal places.) Forecast for period 16 b.Use trend-adjusted smoothing with Cl = .2 and [3 = .'l to smooth the new account data in part a. What is the forecast for period 16? Compute the initial trend estimate {Ttl for Period 5 as follows: (Period 4 data Period 1 data) I 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 and all other intermediate forecast values (TAFt and St) to 2 decimal places. Round your final answer to 2 decimal places.) 9 Answer is complete but not entirely correct. Forecast for period 267.06 a 16
