Requirement 1. determine the company's cost equation (use the output from the excel regression). (round the amounts to two decimal places.) y = $ 0.19 x + $ 2025 requirement 2. determine the r-square (use the output from the excel regression). the r-square is ▼ 0.701995 0.063518 0.751662 0.866985 0.204931 . what does flowers 4 you's r-square indicate? the r-square 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 comma 500 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? (round your answer to the nearest cent.) the operating costs at a volume of 16,500 miles is $ 5160 . should the company rely on this cost estimate? why or why not? since the r-square is ▼ between .50 and .80 less than .50 over .80 , the company ▼ should use the cost equation with caution. can rely on this cost estimate. should not rely on this cost estimate.
