Davidson 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. Requirement 1. Estimate the cost function for the quarterly data using the high-low method. (Complete all answer boxes.) (After you hit continue, the screen may take you below the beginning of the next step. If so, scroll back up to the top of the step.) Goodness of fit: 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. The high-low line appears to "fit" the data well. The vertical differences between the actual and predicted costs appear to be quite small. Slope of high-low line: The slope of the line appears to be reasonably steep indicating that, on average, utility costs in a quarter vary with machine-hours used. 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. Requirement 3. Davidson anticipates that JVR will operate machines for 120,000 hours in quarter 9 . Calculate the predicted utility costs in quarter 9 using the cost function estimated in requirement 1. The predicted maintenance costs would be for quarter 9
