1
Q
What does B(n,p) mean?
A
Binomial distribution of n = number of trials and p = probability of success.
2
Q
Properties of a binomial distribution
A
Each trial only has two outcomes
Each trial is independent
There are a fixed number of trials
3
Q
What is the mean of a binomial distribution?
A
n x p (np)
4
Q
Where are warning limits set?
A
μ ± 2σ
5
Q
Where are action limits set?
A
μ ± 3σ
6
Q
What should you do if a sample mean is between warning and action limits?
A
Take another sample immediately. If this is also between, production should be stopped.
7
Q
What should be done if a sample mean is outside of the action limits?
A
