 |

Hi.
I have a set of numbers. Let say that I have 20 numbers. Lets say that average is 15. How can I find two numbers so that there is 90% probability that any numbers between is complicant with the other 20 numbers?
Eg. If population that counts 20 individuals have a weight of 15 kg in average. How to tell if there is 90 percent probability that any individual has a weight between 13 and 17 kg? (13 and 17 is just random numbers here, it could likely be something else)
