Instead of charging a flat delivery fee, Tran wants to set the delivery fee based on the distance driven to deliver the flowers. Tran 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. She has the following data from the past seven months: (Click the icon to view the data.) Read the Requirement 1. Determine the company's cost equation (use the output from the Excel regression). (Round the amounts to two decimal places.) y=x+ Requirement 2. Determine the R-squared (use the output from the Excel regression). The R-squared is What does Flowers 4 You's R-squared indicate? The R-squared indicates that the cost equation explains of the variability in the data. In other words, it Flowers 4 You feel confident using this cost equation to predict total costs at other volumes within the same relevant range. Requirement 3. 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-squared. Should the company rely on this cost estimate? Why or why not? (Round your answer to the nearest cent.) The operating costs at a volume of 16,000 miles is Should the company rely on this cost estimate? Why or why not? Since the R-squared is the company Data table
