At the beginning of the year, an investor holds EUR10,000 in a hedge fund. The investor borrowed 25 percent of the purchase price, EUR2,500, at an annual interest rate of 6 percent and expects to pay a 30 percent tax on the return she earns from his investment. At the end of the year, the hedge fund reported the information in Exhibit 22:
Exhibit 1:Hedge Fund Investment
The investor's after-tax return on the hedge fund investment is closest to:

Samples of size (n1,n2) are drawn respectively from two populations (X1,X2) with
Associated population means and standard deviations of (μ1,μ2) and (σ1,σ2) where σ1 ≠ σ2. In addition, d is the sample mean of X1−X2 with a standard error of s d and a population mean of μd0 and s2p is a pooled estimator of the common variance.
The most appropriate test statistic to determine the equality of the two population means assuming X1 and X2 are independent and normally distributed is:

An analyst has established the following prior probabilities regarding a company's next quarter's earnings per share (EPS) exceeding, equaling, or being below the consensus estimate.
Several days before releasing its earnings statement, the company announces a cut in its dividend. Given this new information, the analyst revises his opinion regarding the likelihood that the company will have EPS below the consensus estimate. He estimates the likelihood the company will cut the dividend, given that EPS exceeds/meets/falls below consensus, as reported below.
The analyst thus determines that the unconditional probability for a cut in the dividend, P(Cut div), is equal to 23.75%. Using Bayes’ formula, the updated
(posterior) probability that the company’s EPS are below the consensus is closest to:

An investor in Abco stock forecasts the probability that Abco exceeded, met, or fell short of consensus expectations for free cash flow (FCF) during the prior quarter:
P(FCF exceeded consensus) = 0.50 P(FCF met consensus) = 0.35
P(FCF fell short of consensus) = 0.15
While waiting for Abco to release last quarter's FCF data, the investor learns that Abco will acquire a competitor. Believing that the upcoming acquisition makes it more likely that last quarter's FCF will exceed the consensus, the investor generates a list of FCF events that may have influenced the acquisition:
P(Acquisition | FCF exceeded consensus) = 0.40 P(Acquisition | FCF met consensus) = 0.25 P(Acquisition | FCF fell short of consensus) = 0.35
Using Bayes' Formula, calculate the probability that Abco is likely to exceed consensus FCF expectations for last quarter given the acquisition. P(FCF exceeded consensus | Acquisition) is closest to:

An investor currently has a portfolio valued at $700,000. The investor’s objective is long-term growth, but she will need $30,000 by the end of the year to pay her son’s college tuition and another $10,000 by year-end for her annual vacation. The investor is considering three alternative portfolios:
Using Roy's safety-first criterion, which of the alternative portfolios most likely minimizes the probability that the investor's portfolio will have a value lower
Than $700,000 at year-end?

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 noncallable. She then randomly selects bonds from each of the subpopulations she has created. For the manager's sample, which of the following best describes the sampling approach?
