Which of the following statements is true with regard to the high-low method?

		The high-low method is a more accurate method compared to the least-squares regression method because all data points are used when calculating the cost formula.
		The high-low method calculates a cost formula for fixed costs which is the slope of the line using the highest and lowest data points.
		The high-low method is a way to analyze fixed costs based on calculating the slope of a line using all data points.
		The cost formula calculated using the high-low method (and, therefore, only two data points) may misrepresent the true cost behavior during normal periods.
