Webb27 nov. 2024 · If the p-value is less than the significance level, we reject the null hypothesis. So, when you get a p-value of 0.000, you should compare it to the significance level. Common significance levels include 0.1, 0.05, and 0.01. Since 0.000 is lower than all of these significance levels, we would reject the null hypothesis in each case.
