Empirical rule frequency - Study guides, Class notes & Summaries

Probability - Independent Events The occurrence of one event does not affect the probability of the other. -If A and B are independent events, then P(A and B) = P(A)•P(B) Theoretical (Classical) Probability Count the number of outcomes and divide by the total possible outcomes. Theoretical probability requires that the experiment be fair. Empirical Probability (Relative Frequency) Perform the experiment multiple times (trials), count the number of times the event occurs and divided...

BESC 3010 CH 4 QUESTIONS AND ANSWERS | 2024/2025 | GRADED A+ What are the key features of a box plot? A box plot visually summarizes a data set's central tendency, spread, and outliers by displaying the median, quartiles, and extreme values as a rectangular box with "whiskers." How do you interpret skewness in a data distribution? Skewness indicates the asymmetry of a distribution; positive skew means more data points are concentrated on the left, while negative skew suggests...

WGU C955 Exam Questions With 100% Correct Answers 2023 numbers, representing quantities that can be counted or measured. The Empirical Rule - Correct Answer-According to The Empirical Rule, approximately 68% of the data points in a dataset will be within 1 standard deviation of the mean. 95% of all values are within 2 standard deviations of the mean. Normal distribution - Correct Answer-In a normal distribution data is symmetrical, so the mean, median, and mode are all equal. measure o...

Rules of Probability correct answers 1. The probability of any event must be between 0 and 1, inclusive. 0 ≤ P(E) ≤ 1. 2. The sum of the probabilities of all outcomes must equal 1. 3. If E and F are disjoint events, then P(E or F) = P(E) + P(F). If E and F are not disjoint events, then P(E or F) = P(E) + P(F) - P(E and F) 4. If E represents any event and Ec represents the complement of E, then P(Ec) = 1 - P(E) 5. If E and F are independent events, then P(E and F) = P(E)∗P(F) In a pr...

File: ch03, Chapter 3: Descriptive Statistics True/False 1. Statistical measures used to yield information about the center or the middle parts of a group of numbers are called the measures of central tendency. Ans: True Response: See section 3.1 Measures of Central Tendency: Ungrouped Data Difficulty: Easy Learning Objective: 3.1: Apply various measures of central tendency—including the mean, median, and mode—to a set of ungrouped data. 2. The most appropriate measure ...

liquid alternatives - ANSWER-Liquid alternatives typically have (1) constraints on permissible investments strategies (for example, liquidity and leverage limits), (2) no incentive fees, (3) less skilled managers as a result of less attractive compensation and limited strategies, and (4) an inability to earn substantial illiquidity premiums. constrained clone - A liquid investment fund that seeks to replicate the strategy of an existing alternative investment but imposes some constraint (e.g....
