p-Value

Acceptance Domain $A_\alpha$

Interpretation

• Smallest level $\alpha$ which leads to rejecting the Null Hypothesis.
• <

High p-Value of $y$ means that $y$ is typical of random variable $Y$.

For example for an Exponential Distribution small $y$ are more typical. We thus define the p-Value as $p(y)=P(Y\geq y)$ which is small #question.

#todo Second example with Normal Distribution

For Gauß Test:

• at $\mu=\mu_0$ we have Uniform Distribution on $(0,1)$ for the p-Value
