Hello there,
A batch of parts (process follows a normal distribution)
I pick 5 pieces randomly (without replacement)
CASE 1 : What is the probability of having 5 Parts in the interval +/- 2 sigma?
CASE 2 : What is the probability of having 4 parts in the interval +/- 2 sigma and a 1 part in the interval [- 3; -2] Or [2; 3] sigma?
CASE 3 : What is the probability of having 3 parts in the interval +/- 2 sigma and 2 parts in the interval [- 3; -2] Or [2; 3] sigma?
thank you
