9.5.1 General
Given a random variable X, you may want to know whether some
effective parameter p is the same as some expected value p0. You
will then want to test the hypothesis p = p0, which will be the
null hypothesis H0. The alternative hypothesis will be H1. The
tests are:
-
Two-tailed test
- This test will reject the hypothesis H0
if the relevant statistic is outside of a determined interval.
This can be denoted ’!=’.
- Left-tailed test
- This test will reject the hypothesis H0
if the relevant statistic is less than a specific value.
This can be denoted ’<’.
- Right-tailed test
- This test will reject the hypothesis H0
if the relevant statistic is greater than a specific value.
This can be denoted ’>’.
