- Things vary in life virtually nothing (except
physical standards such as the speed of light) we
interact with is constant over time. Much of this
variation follows somewhat predictable patterns
that can be examined using probability

- Discussion 2-1/Hypotheses What is a hypothesis
test? Why do we need to use them to make
decisions about relating sample results to the
population why cant we just make our decisions
by the sample value?
- Variation exists in virtually all parts of our
lives. We often see variation in results in what
we spend (utility costs each month, food costs,
business supplies, etc.). Consider the measures
and data you use (in either your personal or job
activities).
