Just checked Oxford and Macmillan dictionaries. That's not the definition they have though. Here's the definition from Oxford: A supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained. I think the part "especially one based on general principles independent of the thing to be explained" is what seems to be the difference between a hypothesis and a theory. At least, that's the impression I get when I read the definitions of both the words in Oxford.

According to recent PEW polls, average Americans significantly lag behind scientists in all areas of science. This means that the average American does not trust or have confidence in scientists that spent their lives devoted to education, working in their respective fields collecting and analyzing data and subjecting their findings to peer review in scientific journals. While the average American can't be expected to understand scientific data, formulas, equations, and complex analysis, I do believe they can learn to gain better trust in scientific findings by understanding basic concepts used in the scientific method, once they learn it. Just as important is the inability of the average American to discern among scientific and pseudoscientific information widely dispersed on the internet, modern advertisements, and published articles. So far, the scientific method is the best method I know of to develop critical thinking skills without the intent of criticizing an individual's world view or beliefs. At the same time, the Average American will learn the precise meanings of the vocabulary used in science, especially words like hypotheses, theory, evidence, natural laws, findings, verifiable methods, results, pseudoscience, peer review, etc., are used in published scientific findings. The amount of data being collected by scientists studying in every possible location on earth space, is far to for the average scientist to understand, let alone the average American. But, scientists do share an understanding in basic scientific methods, which the average American can learn and develop more confidence in too.

His hypothesis definition is incomplete. An hypothesis is not only testable, but it is also falsifiable. For example, an hypothesis that stated that the universe contained life forms other than life on earth is certainly testable to a certain degree, but it is essentially not falsifiable because the universe is so expansive that even if we never found life in the places that we looked, life could still be elsewhere in the universe.
