Questions 1:
When considering two mutually exclusive capital budgeting projects with conflicting rankings—one has a higher positive net present value (NPV), the other has a higher internal rate of return (IRR)—the most appropriate conclusion is to choose the project with the:
A 、higher NPV
B、 higher IRR.
C、 shorter payback.
Questions 2:
A Type I error is best described as the probability of:
A 、failing to reject a false null hypothesis.
B 、rejecting a true alternative hypothesis.
C 、rejecting a true null hypothesis.
A is correct. The project with the higher NPV should be undertaken because NPV measures the increase in wealth as a result of taking the project. For mutually exclusive projects, IRR may give incorrect decisions as a result of scale and/or cash flow timing effects. Payback is not an economically sound method for evaluation of capital projects.
B is incorrect. When IRR and NPV conflict in ranking, the higher NPV project is chosen.
C is incorrect. Payback suffers from severe deficiencies as a decision tool. In particular, because it is not economically sound, the payback period should not be used to evaluate projects.
C is correct. A Type I error is the mistake of rejecting the null hypothesis when it is, in fact, true.
A is incorrect. This is the definition of a Type II error.
B is incorrect. This is an entirely wrong statement and it is not one of possible outcomes when we test a null hypothesis.
