I'm not sure the problem as you have stated it is well-posed, or
necessarily possible. Suppose there is a true unknown

I think the problem as posed doesn't produce a unique ellipse. You
could start with a circle of radius 0 centered on mean(x),mean(y) and
then increase the radius until it has 95% of the points in it. As long

I can take the results of a simulation with one random variable and
generate
an empirical interval that contains 95% of the observations, e.g.,
Concisely, here is what I am trying to do:

#I post stratify them to 80 type A measurements and 220 type B measurements.
#These measurements tend to be lognormally distributed so I fit them to

I know what get a bigger sample means. I have no clue what ask a more
statistically meaningful question means. Can you elaborate a bit?
