Suppose that you work at a local food manufacturer and are given the task of investigating your company's seasonal sales patterns over the past 10 years (2011 to 2020). After adjusting your sales values for inflation, you calculate the following seasonal sales averages (in millions): Spring: 39 Summer: 46 Fall: 32 Winter: 23 Use this information to seasonally adjust your 2021 Winter sales total of 29 million. Round your answer to two decimal points and omit any units (1.23 NOT $1.23 million).
Which of the following statements related to cost estimation methods is true? O a.

Only high-low method has a slope and an intercept. O c. None of the given answers. O d. The least-squares regression method is the most accurate and reliable method to determine the cost behavior compared to scatter-graph plot and high-low methods. е. The most complex method of cost estimation is the high-low method.
