Freight car loadings over a 12-year period at a busy port are as follows: Week Number Week Number Week Number 1 220 7 350 13 499 2 245 8 360 14 475 3 284 9 423 15 526 4 275 10 380 16 510 5 305 11 425 17 507 6 310 12 450 18 541 a. Determine a linear trend line for expected freight car loadings. (Round your intermediate calculations and final answers to 3 decimal places.) formula110.mml = + t b. Use the trend equation to predict expected loadings for weeks 22 and 23. (Round your intermediate calculations and final answers to 3 decimal places.) The forecasted demand for week 22 and 23 is and respectively. c. The manager intends to install new equipment when the volume exceeds 777 loadings per week. Assuming the current trend continues, the loading volume will reach that level in approximately what week? (Round your intermediate calculations to 3 decimal places and final answer to the nearest whole number.) It would take approximately more weeks.
