Can it be considered as a variant of urn sampling?
say, instead of
colored balls, we'd look at balls of various sizes.
Physically identical - analogy: random sampling
Vary in chemical composition - analog: variation in size
- the sizes of the balls have some distribution
sampling estimate the
Hi to all.
A friend of mine has a problem. The following is my understanding of the
problem.
She has a box of, say, 50 physically identical (to the eye, anyway)
objects, but they vary in chemical composition - there may be half a
dozen or so different compositions in the box. She has another of

that this is a statistical question. To be certain whether the "outside"
object has a composition that
