Outcomes of experiments are predicted to follow
certain probability distributions. This is a testable
hypothesis and is repeatable.

Indeed.

Consider spectral emission lines. These have finite
width due to the uncertainty principle. Does that mean
you can't test hydrogen lines against the theory of
where they should be? Of course not.

There's no more problem with this than with hypothesis
testing of any kind where outcomes are probabilistic.
And as you point out, the outcomes of all exeriments,
even macroscopic ones, are probabilistic.

So where's the problem?
