Webb29 mars 2024 · A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. It indicates strong evidence against the null hypothesis, as there is less than a 5% probability the null is correct (and the results are random). This means we retain the null hypothesis and reject the alternative hypothesis. 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. green country cbd oil price
