WebA hypothesis isn't necessarily right. Instead, it's a "best guess," and the scientist must test it to see if it's actually correct. Scientists test hypotheses by making predictions: if hypothesis X \text X X start text, X, end text is right, then Y \text Y Y start text, Y, end text should be true.
