I conclude that as well.  Earlier in this thread, Tim F. makes a good case
as applied to the question that was the original (?) subject of this
thread:  determining the uncertainty in the impact location of a marble
launched horizontally with some velocity and falling some vertical
distance.  I'm still thinking about it, but I lean towards thinking my
original statement about using standard deviation of the mean was incorrect.

This could be a misunderstanding on my part.  I thought that you did Monte
Carlo using a distribution that best represented your sample.  Is Monte
Carlo always done using Gaussian distributions, so that what I said was
redundant?
