Review comment:
This kind of a weird test, as it's almost asserting the CDF is in [0,1]
which is true by definition. For symmetry, I'd change the lower bound to be
smaller too, to match. Did the upper bound need to be this large? it doesn't
indicate a problem, but just checking as that one is a little surprising. I
don't think it indicates a bug.
