Answer
Brief Explanations:
A hypothesis in the scientific method must be testable so that experiments can be designed to prove or disprove it. Repeatability is related to the experiment testing the hypothesis, not a requirement of the hypothesis itself. It doesn't have to be written, and it doesn't have to be supported as it is a proposed explanation before testing.
Answer:
testable.
