Which of the following statements related to cost estimation methods is true? O a. None of the given answers. O b. The three methods determine a slope and an intercept. Oc The scatter-graph method is used to derive an estimated line of cost behavior by graphically connecting the two cost amounts identified with the highest and lowest volume levels. Od. The most complex method of cost estimation is the high-low method. e. The high-low method is the most accurate and reliable method to determine the cost behavior compared to scatter-graph plot and Teast-squares regression methods
