Other commonly used significance levels are 0.01 and 0.001. In his seminal paper, ... when the p-value is less than α, the null can be rejected and the alternative hypothesis accepted. The p-value is widely used in statistical hypothesis testing, specifically in null hypothesis significance testing. In this method, before conducting the study, one first chooses a model (the null hypothesis) and the alpha level α (most commonly .05). After analyzing the data, if the p-value is less than α, that is taken to mean that the observed data is sufficiently inconsistent with the null hypothesis for the null hypothesis to be rejected.
