Data table Requirements Use Microsoft Excel to run a regressilaranalysis, then do the following: 1. Determine the company's cost equation (use the output from the Excel regression). 2. Determine the R-squared (use the output from the Excel regression). What does Flower Direct's R-squared indicate? 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? Requirement 1. Determine the company's cost equation (use the output from the Excel regression).
