If an analyst expects a portfolio to outperform its benchmark with a 75% success rate in any measurement period, and the portfolio meets that objective in three of four quarters, what is the probability that the realized portfolio performance over the year is at or below this expectation?
0.26
B0.42
C0.68
drawing an equal number of simple random samples from each subpopulation.
Bselecting every kth member of the population until the desired sample size is reached.
Cdrawing simple random samples from each subpopulation in sizes proportional to the relative size of each subpopulation.
The rejection region increases in size as the level of significance becomes smaller.
BA one-tailed test more strongly reflects the beliefs of the researcher than a two-tailed test.
CThe absolute value of the rejection point is larger than that of a two-tailed test at the same level of significance.
It is a less precise measure of test evidence than rejection points.
BIt is the largest level of significance at which the null hypothesis is rejected.
CIt can be compared directly with the level of significance in reaching test conclusions.
Which of the following represents a correct statement about the p-value?
The p-value offers less precise information than does the rejection points approach.
BA larger p-value provides stronger evidence in support of the alternative hypothesis.
CA p-value less than the specified level of significance leads to rejection of the null hypothesis.
Why is technical analysis especially useful in the analysis of commodities and currencies?
Valuation models cannot be used to determine fundamental intrinsic value for these securities.
BGovernment regulators are more likely to intervene in these markets.
CThese types of securities display clearer trends than equities and bonds do.
If n is large and the population standard deviation is unknown, the standard error of the sampling distribution of the sample mean is equal to:
the sample standard deviation divided by the sample size.
Bthe population standard deviation multiplied by the sample size.
Cthe sample standard deviation divided by the square root of the samplesize.
