Question 7 Which of the following is/are true? Group of answer choices b) As DOL rises, expected EPS rises c) As DOL rises, expected coefficient of variation falls a) As DOL rises, fixed costs as a percentage of total costs increases None of the other answers is true All of the above are true
Which of the following is not true about depreciation? Group of answer choices It is a non-cash expense. It affects corporate taxes. It does not affect net income. All of these are true.
Which of the following is a true statement? Group of answer choices A cost pool is the value of a group of costs used to make a single product. Unit cost is the value assigned to a cost object based on a percentage of the sales price. A cost object always equals one unit of production. Cost drivers are used to determine when and how much overhead to allocate to work in process.
Which of the following is not true concerning TCA? Group of answer choices Organisms that do not have the full TCA cycle will still have many of its enzymes. It begins with acetyl-CoA being combined with citrate. It produces pyruvate as a major product. It is important for generating many of the 12 carbon skeletons. None of the above are incorrect.
Which of the following statements is true? Group of answer choices A.an unbiased estimator is consistent if its variance goes to zero as the sample size gets large. B.a biased estimator is consistent if its bias goes to zero as the sample size gets large. C. a consistent estimator is biased in small samples. D.all unbiased estimators are consistent. E. all consistent estimators are unbiased.
Which of the following statements about experiments is true? Group of answer choices None of these is true. All experiments must have a control group. Random assignment is only critical for treatment groups, as opposed to control groups. Matching can be used in any experiment to eliminate lurking variables. Blocking is employed to reduce variation.
