2020年你是否已經(jīng)做好準(zhǔn)備了呢？為參加zui后一次CFA筆考而努力呢？今天小編給你準(zhǔn)備了一些CFA考題，看看你能不能將其作對(duì)呢？

1. What are the mean and standard deviation of a standard normal distribution?

Mean Standard deviation

    A 0 0

    B 0 1

    C 1 0

    D 1 1

    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(shí)間，認(rèn)真的備考CFA考試是對(duì)自己的負(fù)責(zé)，那你是不是沒(méi)有資料學(xué)習(xí)呢？
