1、A discrete uniform distribution consists of the following twelve values:On a single draw from the distribution, the probability of drawing a value between -2.0 and 2.0 from the distribution is closest to:【单选题】
A.16.67%.
B.18.04%.
C.27.59%.
正确答案:A
答案解析:“Common Probability Distributions,” Richard A. Defusco, CFA, Dennis W. McLeavey, CFA, Jerald E. Pinto, CFA, and David E. Runkle, CFA2011 Modular Level I, Vol. 1, pp. 497-498Study Session 3-9-fCalculate and interpret probabilities given the discrete uniform and the binomial distribution functions.First order the values from smallest to largest.Then note that two of the twelve values are between -2.0 and 2.0. Thus, the probability of a draw from the distribution being between -2.0 and 2.0 is 2/12 = 0.16667.
2、A two-tailed t-test of the null hypothesis that the population mean differs from zero has a p-value of 0.0275. Using a significance level of 5%, the most appropriate conclusion is:【单选题】
A.reject the null hypothesis.
B.accept the null hypothesis.
C.the chosen significance level is too high.
正确答案:A
答案解析:“Hypothesis Testing,” Richard A. DeFusco, Dennis W. McLeavey, Jerald E. Pinto, and David E. RunkleA is correct. The p-value is the smallest level of significance at which the null hypothesis can be rejected. In this case, the given p-value is less than the given level of significance and we reject the null hypothesis.
3、Given a large random sample, which of the following types of data are least appropriately analyzed with nonparametric tests?【单选题】
A.Ranked data (e.g., 1st, 3rd)
B.Signed data (e.g., number of +'s and –'s)
C.Numerical values (e.g., 28.43, 79.11)
正确答案:C
答案解析:Nonparametric tests are primarily concerned with ranks, signs, or groups, and they are used when numerical parameters are not known or do not meet assumptions about distributions. Even if the underlying distribution is unknown, parametric tests can be used on numerical data if the sample is large.Section 5
4、A group of fund analysts have to select the first, second, and third best fund manager of the year for 2012 based on their subjective judgment. If 10 fund managers are candidates for the three awards, the number of ways in which each analyst can make his ranking is closest to:【单选题】
A.120.
B.30.
C.720.
正确答案:C
答案解析:This problem is a counting one in which order does matter.For this reason, use the permutation formula ,wheren is the total number of fund managers; in the problem, n = 10.r is the number of fund managers that will receive the awards (first, second, and third); in the problem, r = 3.There are 720 ways that each analyst can rank 3 fund managers out of 10, when order does matter.2014 CFA Level I“Probability Concepts,” by Richard A. DeFusco, Dennis W. McLeavey, Jerald E. Pinto, and David E. RunkleSection 4.2
5、The unemployment rate is best described as the ratio of unemployed to:【单选题】
A.labor force minus frictionally unemployed.
B.total population of people who are of working age.
C.labor force.
正确答案:C
答案解析:The unemployment rate is the ratio of unemployed to labor force.Section 4.1
6、An analyst gathers the following information about a company’s common stock:To calculate earnings per share for 2011, the company’s weighted average number of shares outstanding is closest to:【单选题】
A.333,333.

A.one-tailed test and can reject his null hypothesis.
B.two-tailed test and can reject his null hypothesis.
C.two-tailed test and can not reject his null hypothesis.
