WebApr 9, 2024 · If the p-value of a hypothesis test is sufficiently low, we can reject the null hypothesis. Specifically, when we conduct a hypothesis test, we must choose a significance level at the outset. Common choices for significance levels are 0.01, 0.05, and 0.10. If the p-values is less than our significance level, then we can reject the null hypothesis. WebWe use p p -values to make conclusions in significance testing.
