What are the conditions for a poisson distribution?
Random events
Independent events
Constant average rate
Limitless
How do you find exact probilities?
By using poisson pd mode on the calculator
How do you use the number line for inequality questions?
P( x <, >) - > you have to use the number line to rearrange the inequality so it is p(x\<....)
How do you scale a poisson distribution?
1 hour - lambda
2 hours - lambda +lambda
3 hours lambda + lambda + lambda
How do you tell the difference between a poisson distribution and a binomial distribution?
Poisson-limitless nature, constant average rate
Binomial - fixed # of trials, same probability
How the mean and variance of a Poisson inform us on the suitability of the Poisson Distribution?
When the observed means and variances are similar to the expected means and variances
