Web19 apr. 2024 · Our significance level is usually set at 0.05, which equates to 5%. So if a p-value comes in at 0.12, or 12% — we say we fail to reject the null hypothesis and most … WebWe have to divide the significance percentage between the two tails. For example, with a 5% significance level, we reject the null hypothesis only if the sample is so extreme that it is in either the top 2.5% or the bottom 2.5% of the comparison distribution.
