Continuous Probability Distributions Ch 6

QuestionAnswer
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
