UUS Hot Indicale completion Problem 3-7 Freight car loadings over an 18-week period at a busy port are as follows: Week Week 1 2. 3 4 Number 290 300 310 300 310 315 7 8 9 10 11 12 Number 335 375 415 405 445 485 Week 13 14 15 16 17 18 Number 490 495 515 525 535 545 5 6 a. Determine a linear trendline for expected freight car loadings. (Round your intermediate calculations and final answers to 2 decimal places.) 7 = 410.55 17.40 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 593.25 and for Week 21 is 610.64 c. The manager intends to install new equipment when the volume exceeds 870 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 870 loadings in Week 26.41 3 of 6 MacBook Pro
