Statistics 1060: Hypothesis Testing

5 PARTS OF THE HYPOTHESIS TEST


1. STATE NULL HYPOTHESIS (H0)

2. STATE ALTERNATIVE OR RESEARCH HYPOTHESIS (HA)

3. CALCULATE THE TEST STATISTIC (T.S.)

4. FIND THE P-VALUE (LEVEL OF SIGNIFIGANCE)

5. DRAW CONCLUSIONS


THE SMALLER THE P-VALUE, THE STRONGER THE EVIDENCE AGAINST THE NULL HYPOTHESIS (H0)


\begin{displaymath}\begin{array}{cc} \underline{p-value} & \underline{strength \... ...ry \ strong \\ p \le 0.001 & very, \ very \ strong \end{array}\end{displaymath}


TO TEST AT LEVEL $\alpha$

Reject H0 if the p-value is less than or equal to $\alpha$.

If the p-value is larger than $\alpha$, do not reject H0.
