A statistical hypothesis is an assumption about a population parameter. A hypothesis in physics is something else entirely. (Incidentally, there are hypotheses in mathematics, too, called "conjectures"). You may disagree, but I see statistics as a science, akin to physics; which, perhaps, is why we also have "mathematical statistics."
Well both are statements that can be true or false.
I would say in physics it's also a population parameter. It's just sometimes we feel so confident about a single observation that we only need to take 1 sample.

I don't disagree. This has been my entire point. I define statistics as the foundational formal definition of the scientific method.
