Millionaires are Baby Boomers (or Older) For most Americans, incomes tend to rise with age and experience. Thus, it is not surprising that in 2009, 80 percent of millionaires were older than age 45 and close to half of all millionaires (46 percent) were older than age 55.
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it.
Theory is different from a hypothesis. Hypothesis is merely an idea or a concept, which is not scientifically analyzed. These are the assumptions made by scientists before an investigation. However, once the hypotheses are analyzed and proved to be correct, they are recognized as theories.
