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  
🗑
