C 1 0

Answer: B. The standard normal distribution (unit normal distribution) has a mean of zero and a standard deviation deviation of one
2. The population mean and standard deviation of monthly net sales for a company are $100 million and $30 million, respectively. if monthly net sales are normally distributed, which of the following best describes the interval that would be expected to contain approximately 95 percent of the monthly net sales?
A. ＄10 million to ＄190 million.
B. ＄30 million to ＄170 million.
C. ＄40 million to ＄160 million.
D. ＄70 million to ＄130 million.
Answer: C. In normal distribution, about 95 percent of the observations will fall within standard deviations of the mean ＄100-2*(30)=＄40and ＄100+2*(30)= ＄160
3. A mutual fund manager wants to create a fund based on a high-grade corporate bond index. She first distinguishes between utility bonds and industrial bonds; she then for each segment defines maturity intervals of less than 5 years, 5 to 10 years, and greater than 10 years. For each segment and maturity level, she classifies the bonds as callable or non-callable. For the manager’s sample, which of the following best describes the
Sampling approach Number of sampling cells?
A Simple random sample 3
B Simple random sample 12
C Stratified random sample 3
D Stratified random sample 12
Answer: D.The mutual fund manager is using a stratified random sampling approach with 12 cells: 2*3*2=12 sampling cells
畢竟現(xiàn)在距離CFA考試還有一段時間，認(rèn)真的備考CFA考試是對自己的負(fù)責(zé)，那你是不是沒有資料學(xué)習(xí)呢？
