Chad Richardson, financial analyst at MVR Corporation, is examining the behavior of quarterly utility costs for budgeting purposes. Richardson collects the following data on machine-hours worked and utility costs for the past 8 quarters (Click the icon to view the data.) Read the requirements. 1 Data Table Quarter Machine-Hours Utility Costs 125,000 $ 80,000 115,000 130,000 95,000 120,000 110,000 105,000 245,000 180,000 230,000 270,000 200,000 250,000 255,000 225,000 2 3 4 6 8 1 Requirements 1. 2. 3. Estimate the cost function for the quarterly data using the high-low method. Plot and comment on the estimated cost function. Richardson anticipates that MVR will operate machines for 130,000 hours in quarter 9. Calculate the predicted utility costs in quarter 9 using the cost function estimated in requirement 1 Requirement 1. Estimate the cost function for the quarterly data using the high-low method.

Economic plausibility: O The cost function shows a negative economically plausible relationship between machine-hours and utility costs. There is not a clear-cut O 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. relationship of higher machine-hours and utility costs Goodness of fit: O The high-low line appears to "fit" the data well. The vertical differences between the actual and predicted costs appear to be quite small. O The high-low line appears to not "fit" the data well. The vertical differences between the actual and predicted costs appear to be quite large Slope of high-low line O The slope of the line appears to be reasonably steep indicating that, on average, utility costs in a quarter vary with machine-hours used O The slope of the line appears to be unreasonably steep indicating that, on average, utility costs in a quarter do not vary with machine-hours used.
