Determine the fixed costs and unit variable costs using regression analysis (We recommend the use of Excel.) (Round fured cost to 3 decimal places es. 1.252 and variable cost to 5 decimal places es. 1.25125.) Fixed costs Unit variable costs $ /machine hour The controller of Cullumber Industries has collected the following monthly cost data for analyzing the behavior of electricity costs. \begin{tabular}{lcc} & \begin{tabular}{c} Total \\ Electricity Costs \end{tabular} & \begin{tabular}{c} Total \\ Machine Hours \end{tabular} \\ January & $2,370 & 230 \\ February & 3,100 & 370 \\ March & 3,460 & 450 \\ April & 4,540 & 695 \\ May & 3,240 & 400 \\ June & 4,960 & 770 \\ July & 4,150 & 625 \\ August & 3,910 & 510 \\ September & 5,000 & 665 \\ October & 4,270 & 610 \\ November & 3,280 & 370 \\ December & 6,050 & 790 \end{tabular} What electricity cost does the cost equation estimate for a level of activity of 450 machine hours? Round unit cost and finol answers to 2 decimal placeres. 1,250.25. Electricity costs By what amount does this differ from March's observed cost for 450 machine hours? (Round answer to 2 decinsi ploces es. 1.25) Amount differ
