An asset-pricing model that attempts to explain how investors should behave is a(n): - Answer normative model. Normative models attempt to explain how investors should behave. Positive models attempt to explain how investors do behave. Theoretical models use assumptions and logic, while empirical models are based on historically observed behavior. Henry Thompson examines a sample of returns for a private equity fund and finds that the sample excess kurtosis equals 3. Regarding the private ...

Alicia would like to know if there is a difference in the average price between two brands of shoes. She selected and analyzed a random sample of 40 different types of Brand A shoes and 33 different types of Brand B shoes. Alicia observes that the boxplot of the sample of Brand A shoe prices shows two outliers. Alicia wants to construct a confidence interval to estimate the difference in population means. Is the sampling distribution of the difference in sample means approximately normal? - Yes,...

Ex post returns - ANSWER-- are realized outcomes rather than anticipated outcomes ex ante returns - ANSWER-- future possible returns and their probabilities normal distribution - ANSWER-- is the familiar bell shaped distribution, also known as the Gaussian distribution - is symmetric, meaning the left and the right sides are mirror images of each other. - also, it peaks (or clusters) near the center, with decreasing probabilities of extreme events lognormal distribution - ANSWER-- a...

Statistics - The most important goal of statistics is to infer an unknown quantity (e.g., height of a species of plant) of an entire population of plants based on sample data (a subset of observations from the population) Population - Entire collection of individual units that share a property or sets of properties from which you want to generalize knowledge about unknown quantities (observations) based on a sub-set of individual units (sample). Parameter - a quantity describing a statisti...
