Which of the following statements related to cont estimation methods is trun? O. The most complex method of cost estimation is the high-low method On The scatter-graph method is used to derive an estimated line of cost entor by graphically connecting the two cost amounts identified with the highest and lowest volume level O The high-low method is the most accurate and reliable method to determine the cost beluvior compared to scatter-graph plot and least one regression methods Od None of the given inwers The three methods determine stope and an intercept.
