*TScal — the observed (calculated) value of the test statistic.*

Step 4 · Formulating the decision rule

TScal — the observed (calculated) value of the test statistic.

TScr — the critical value of the test statistic for the chosen significance level.

If the probability of TScal < significance level (α) , then reject H₀ .

or

If TScal > TScr , then reject H₀ .
