数量，reading8，关于F检验。 F=MSR/MSE，或=(SSR/k)/[SSE/(n-1-k)] 两种计算方法应该都可以，为什么原版书课后题的答案里，多采用后一种算法，考试中该如何选择？请教老师，感谢！

Erin Chou is reviewing a profitable investment project that has a conventional cash flow pattern. If the cash flows for the project, initial outlay, and future after-tax cash flows all double, Chou would predict that IRR would: a. increase and the NPV would increase b. stay the same and the NPV would increase c. stay the same and the NPV would stay the same 没太懂为什么选b
已回答An investment of $20000 will create a perpetual after-tax cash flow of $2000. The required rate of return is 8 percent. What is the investment's profitability index? A. 1.08 B. 1.16 C 1.25 这道题我看了答案解析，求pv时用的是2000/0.08 而不是2000/（1+0.08）是为什么呢？pv不是等于future cash flow/(1+r)^t，这里的分母为什么没有+1呢？
