Now,to pull three samples from this population which has mean = 50, sigma = 10:

MT B >Name C2'Subgp1'
MT B >Name C3'Subgp2'
MT B >Name C4'Subgp3'
MT B >Random 25C2 - C4
SUBC>Normal5010
MT B >Desc C2 -C4

Note that the means are close,but not exactly the same.

Note also thatthe StDevs are close, but not exactly the same.

T here are two ways to estimate what the parent population lookslike.
(Itactually is a normal distn,with mean = 50 and S = 10,but we aren't supposed to know that yet).
