STA Class 13:55:23 To find Poisson Probabilities o 1. Point probability formula o 2. Poisson tables (pg 889 – 893, cumulative) o Ex. A certain stretch of I-4 has an average of 3 accidents per day. What is the probability of: fig 4.5-3 1. Exactly 1 accident today? 2. At least 3 accidents today? Example #4 o The number of births per day at Arnold Palmer Hospital for Women and Children has a Poisson distribution with mean 9. Fig 4.5-4 A. what is the probability that exactly 6 births would occur today? B. what is the probability that more than 7 births would occur today? Summary Ch. 4 o Discrete Distributions (general, binomial and Poisson). Know characteristics o Distinguish between the 3 types of discrete r.v.’s o Find probabilities for discrete r.v. by using formulas and/or tables. Ch. 5 Continuous Random Variables o Continuous—can assume any value within some intgerval o We will cover uniform (equally likely outcomes), normal (bell shaped), and exponential. o
