Which of the following five steps (out of six) of cost estimation is out of order? A. Step 1: Define the cost object to be estimated. B. Step 2: Determine the cost driver(s). C. Step 3: Collect relevant data on the cost of the cost object and the cost driver. D. Step 4: Evaluate the accuracy of the cost estimate. E. Step 5: Graph the data. The identification of cost drivers is perhaps the most important step in developing the cost estimate because: A. It is the first step in cost estimation. B. It is the final step in cost estimation. C. There may be a number of relevant drivers, some not immediately obvious. D. The other steps are easier to execute. E. It requires much more time than the other steps. 3. Regression analysis is better than the high-low method of cost estimation because regression analysis: A. Is mathematical. B. Can provide greater precision and reliability. C. Fits data into a mathematical equation. D. Takes less time. E. Is a statistical method
