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 statement that explains a set of facts and can be tested to determine if it is false or inaccurate. Usage The words hypothesis, law, and theory refer to different kinds of statements that scientists make about natural phenomena. A hypothesis is a statement that attempts to explain a set of facts. It forms the basis for an experiment that is designed to test whether it is true. Suppose your friend Smedley's room is a mess; your hypothesis might be that Smedley makes the room messy.
