What do you mean by "value"?
Certainly, if a theory is supposed to have scientific value (if it tells us something new about the world around us), there must be evidence to support it, or else it were a bad theory (or actually not a real theory at all).
However, every scientific theory starts off as a hypothesis, which is basically just a "quaint idea". By testing that hypothesis (and obtaining positive results), it might actually be developed into a real theory. If the evidence speaks against the hypothesis, the idea just dies right there (or at least it should).
So, a hypothesis has to be testable to have value (so it can "grow" into a theory).
It must be possible to observe whether the hypothesis is true.
True. For a hypothesis to have value, it must be testable, meaning it can be supported or refuted through experimentation or observation. This testability allows researchers to gather evidence and draw conclusions, ultimately contributing to the advancement of knowledge in a particular field. Without being testable, a hypothesis remains speculative and cannot be scientifically validated.
The hypothesis must be able to be proved true or false.
A testable hypothesis is one which you can formulate an experiment around. In simpler terms, a testable hypothesis is one you can test to see if it is true or not.
It is testable and falsifiable

The hypothesis must be able to be proved true or false.
A scientific theory or hypothesis must be able to make predictions that can be tested. It must be possible to design an experiment so that there is one outcome if the hypothesis is true and a different outcome if it is false. This is what is meant by saying that a hypothesis is testable or falsifiable. If such as experiment is carried out and the outcome is not as predicted then the hypothesis must be rejected and replaced by an alternative hypothesis - or a modified version.
A hypothesis is testable when we can determine experientially whether it is likely to be false or more likely to be true. That means we must be able to distinguish between it being true or false observationally. Thus, equally important to finding observations that confirm the hypothesis, we must be able to specify what it is we expect to see in the case that the hypothesis is false: the hypothesis must be falsifiable in order to be testable.It must be able to be proved right or wrong.
It must be possible to observe whether the hypothesis is true.
It must be proven from right to wrong
"A hypothesis is a proposed answer to a question. To answer the question raised by your observations, the hypothesis must be testable." it means that you need to be able to prove that your hypothesis is true or not by creating an experiment and collect/analyze the data
