What is the difference between the null and alternative hypotheses statements in one-tailed and two-tailed tests?
---
Two-tailed tests
null is a statement of equality
alternate is a statement of inequality
----------------------------
One-tailed test:
null is a statement of equality
altenate is a greater than or less than statement.
-----------------------------
How do ethics affect your chosen level of significance
Level of significance should be low (<= 1%) if people's
health or severe economic impact might result from rejecting
the null hypothesis.
--------------------------
Level of significance can be higher (>= 10%) if the consequences
of rejection are lower.
