capacity; actual usage was 52 percent of capacity. A smoothing constant of .20 is used. a. Prepare a forecast for September. (Round your final answer to 2 decimal places.) Forecast for September percent of capacity b. Assuming actual September usage of 59 percent, prepare a forecast for October usage. (Round your answer to 2 decimal places.) Forecast for October percent of capacity/nok ences Freight car loadings over an 18-week period at a busy port are as follows: Week Week 1 7 Mc Graw Hill 2 3 4 5 6 Number 340 345 350 345 350 355 8 9 18 11 12 Number 405 445 485 t 480 520 560 Week 13 14 15 16 17 18 Number 565 570 620 625 630 635 a. Determine a linear trend line for expected freight car loadings. (Round your intermediate calculations and final answers to 2 decimal places.) Ý=[ b. Use the above trend equation to predict expected loadings for Weeks 20 & 21. (Round your final answers to 2 decimal places.) The forecasted demand for Week 20 is and for Week 21 is c.
