TAILIEUCHUNG - Lecture Statistical techniques in business and economics: Chapter 6 - Lind, Marchal, Wathen

When you have completed this chapter, you will be able to: Define the terms probability distribution and random variable; distinguish between discrete and continuous random variables; calculate the mean, variance, and standard deviation of a discrete probability distribution; describe the characteristics and compute probabilities using the Poisson probability distribution. | Discrete Probability Distributions Chapter 6 Define the terms probability distribution and random variable. Distinguish between discrete and continuous probability distributions. Calculate the mean, variance, and standard deviation of a discrete probability distribution. Describe the characteristics of and compute probabilities using the binomial probability distribution. Describe the characteristics of and compute probabilities using the hypergeometric probability distribution. Describe the characteristics of and compute probabilities using the Poisson probability distribution. GOALS What is a Probability Distribution? Experiment: Toss a coin three times. Observe the number of heads. The possible results are: Zero heads, One head, Two heads, and Three heads. What is the probability distribution for the number of heads? PROBABILITY DISTRIBUTION A listing of all the outcomes of an experiment and the probability associated with each outcome. CHARACTERISTICS OF A PROBABILITY .
