All of the following statements are false except: O a. The highest and lowest costs are always used to analyze a mixed cost under the high-low method. b. A major advantage of the high-low method of cost estimation is that it omits all data from the analysis other than the lowest and highest costs. OC. The high and low points used in the high-low method tend to be unusual and therefore the cost formula for the mixed cost may not accurately represent all of the data. Od The engineering approach to the analysis of mixed costs involves a sa detailed statistical analysis of cost behavior using methods that minimize the squared errors. e. All of the given statements are false
