(Click the icon to view the data.) Requirements 1. Estimate the cost function for the quarterly data using the high-low method. 2. Plot and comment on the estimated cost function. 3. Howard anticipates that JVR will operate machines for 75,000 hours in quarter 13 . Calculate the predicted maintenance costs in quarter 13 using the cost function estimated in requirement 1. 4. Would there be much value to estimating the cost function using the regression method instead of the high-low method used in requirement 1 ? Explain. Requirement 1. Estimate the cost function for the quarterly data using the high-low method. (Complete all answer boxes. Round the slope coefficient to two decimal places.)
