WebTo determine whether the difference between the population means is statistically significant, compare the p-value to the significance level. Usually, a significance level (denoted as α or alpha) of 0.05 works well. A significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. WebA p-value simply tells you the strength of evidence in support of a null hypothesis. If the p-value is less than the significance level, we reject the null hypothesis.
