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.
Theory. A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven.
A hypothesis is essentially an idea- based on what you know and have observed, what you think is going on. A theory is a hypothesis that has been backed up by evidence and experimentation. Unfortunately, in layman's terms, a theory is often thought to mean a guess, which is not true. When someone talks about a theory outside a scientific context, they usually mean a hypothesis.
