Continuous Probability Distributions Ch 6
Question | Answer |
---|---|
Continuous Probability Distributions | Can assume any value in an interval on the real line or in a collection of intervals. |
Continuous Probability Distributions II | It is not possible to talk about the probability of the random variable assuming a particular value. |
Continuous Probability Distributions III | We talk about the probability of the random variable assuming a value within a given interval. |
Continuous Probability Distributions IV | The probability of the random variable assuming a value within some given interval from X1 to X2 is defined to be the area under the graph of the probability density function between X1 and X2. |
Standard Normal Distribution | A normal distribution in which the mean is 0 and the standard deviation is 1. It is denoted by z. |
Z-score | Also known as z-value. A standardized score in which the mean is zero and the standard deviation is 1. The Z score is used to represent the standard normal distribution. |
Poisson distribution | provides an appropriate description of the number of occurrences per interval |
Exponential distribution | provides an appropriate description of the length of the interval between occurrences |
