Runkle, CFAMean = ($230,000 + 480,000) / 2 = $355,000. 99 percent of observations under a normal distribution will be plus/minus three standard deviations. Thus, ($355,000 - $230,000)/3.0 = $41,667. It is also the case that ($480,000 - $355,000)/3.0 = $41,667.

C.$ 18.50

正確答案:C

答案解析:N = 8, I/Y = 5, PMT = $1 000 × 6%/2 = $30, FV = $1 000，求出PV = $1035.85，當(dāng)利率改變時(shí)，N = 8，I/Y = 4.5，PMT = $1 000 × 6%/2 = $30，F(xiàn)V = $1 000，求出PV =$1 054.35，因此利率從5%變化為4.5%時(shí)，價(jià)格上升了$1 054.35 - $1035.85 =$18.50。
