Detailed explanation-1: -Hypothesis: A testable prediction often implied by a theory.
Detailed explanation-2: -A hypothesis is a specific, testable prediction or claim about what you expect to observe, given a set of circumstances. A theory is a broader statement used to account for an existing body of knowledge and to also provide unique predictions to extend that body of knowl-edge.
Detailed explanation-3: -A research hypothesis is a more precise and testable statement, such as, “People who smoke cigarettes regularly will have a higher incidence of lung cancer over a 10-year period than people who do not smoke cigarettes.”
Detailed explanation-4: -All predictions should be testable, meaning it should be possible to design an experiment that would verify or invalidate the prediction. With the solvent, for example, you could test your prediction by dissolving different compounds in water at different temperatures and measuring the solubility.
Detailed explanation-5: -Outside science, a theory or guess can also be called a hypothesis. A hypothesis is something more than a wild guess but less than a well-established theory. In science, a hypothesis needs to go through a lot of testing before it gets labeled a theory. In the non-scientific world, the word is used a lot more loosely.
