WebS.3.2 Hypothesis Testing (P-Value Approach) The P -value approach involves determining "likely" or "unlikely" by determining the probability — assuming the null hypothesis were true — of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed. If the P -value is small, say less than (or ... WebJan 21, 2024 · Rather than having formal rules for when to reject the null hypothesis, one can report the evidence against the null hypothesis.
