Kaitlyn Coughlin, owner of Flower Direct, operates a local chain of floral shops. Each shop has its own delivery van. Instead of charging a flat delivery fee, Coughlin wants to set the delivery fee based on the distance driven to deliver the flowers. Coughlin wants to separate the fixed and variable portions of her van operating costs so that she has a better idea how delivery distance affects these costs. Flower Direct does a regression analysis on the next year's data using Excel. The output generated by Excel is as follows: :: (Click the icon to view the regression analysis.) Requirements 1. Determine the firm's cost equation (use the output from the Excel regression) 2. Determine the R-square (use the output from the Excel regression). What does Flower Direct's R-square indicate? Requirement 1. Determine the firm's cost equation (use the output from the Excel regression) (Enter amounts to two decimal places) y=sLX+ SL Question Viewer Regression analysis SUMMARY OUTPUT Regression Statistics Multiple R 0.86 R Square Adjusted R Square 0.70 Standard Error 174.75 Observations 0.75 ANOVA SS MS Significance F 0.0122 Regression 14.69 448,647.94 152,694.92 448,647.94 30,538.98 Residual 501,342.86 Total Lower Upper 95 Standard Error 1.131.33 0.07 Intercept 1028.28 Star 0.91 3.83 P.value 0.41 0.01 1.879.90 3,936.46 0.090 .43 X Variable 1 0.26 Requirements 1.

Predict van operating costs at a volume of 16,000 miles assuming the company would use the cost equation from the Excel regression regardless of its R-square. Should the company rely on this cost estimate? Why or why not
