Comment on the estimated cost function by choosing the correct statement to go with each of the evaluation criteria listed below. Economic plausibility: The cost function shows a positive economically plausible relationship between machine-hours and utility costs. There is a clear-cut relationship of higher machine-hours and utility costs. Goodness of fit: The high-low line appears to "fit" the data well. The vertical differences between the actual and predicted costs appear to be quite small
