Problem 3-7 Freight car loadings over an 18-week period at a busy port are as follows: Week Number Week Number Week Number 1 300 7 365 13 485 305 8 395 14 490 3 310 9 425 15 540 305 10 420 16 545 310 11 450 17 550 315 12 480 18 555 a. Determine a linear trend line for expected freight car loadings. (Round your intermediate calculations and final answers to 2 decimal places.) Y 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. The manager intends to install new equipment when the volume exceeds 880 loadings per week. Assuming the current trend continues, in which week (at the earliest) should the loading volume reach that level? (Use the rounded answers, as required, from any previous part of this problem. Do not round any other intermediate calculations. Round your final answer to 2 decimal places.) It should reach 880 loadings in Week
