e best correct answer rate of return for a given project is 11%, the net present worth for this project at an interest rate of %: A. Will be a negative value B. Will be a positive value C. Can be a negative or a positive value D. None of the above is correct 2. The main focus of the "bottom-up" estimating approach is to estimate cost elements: A. At the higher levels of the WBS cost structure, which are then added together to obtain the total cost of the product/project and, therefore, determine what should the product cost B. At the lower levels of the WBS cost structure, which are then added together to obtain the total cost of the product/project and, therefore, determine what should the product cost C. At the lower levels of the WBS cost structure, which are then added together to obtain the total cost of the product/project and, therefore, determine what does the product cost D. At the higher levels of the WBS cost structure, which are then added together to obtain the total cost of the product/project and, therefore, determine what does the product cost 3. Selecting the project that maximizes the B/C ratio: A. Guarantees that the selected project is the most profitable one B. Guarantees that the best project is selected C. Does not guarantee that the best project is selected D. Indicates that the incremental B/C ratio for this project as compared to all other projects will be higher than one A. The estimate becomes less accurate and the cost of estimating increases B. The estimate becomes less accurate and the cost of estimating decreases C. The accuracy of the estimate improves and the cost of estimating decreases D. The accuracy of the estimate improves and the cost of estimating increases 4. As the estimate becomes more detailed
