WebJun 15, 2024 · In order to reject the null hypothesis, it is essential that the p-value should be less that the significance or the precision level considered for the study. Hence, Reject null hypothesis (H0) if ‘p’ value < statistical significance (0.01/0.05/0.10) Accept null hypothesis (H0) if ‘p’ value > statistical significance (0.01/0.05/0.10) WebIf we fail to reject the null hypothesis, it does not mean that the null hypothesis is true. That's because a hypothesis test does not determine which hypothesis is true, or even which one is very much more likely. What it does assess is whether the evidence available is statistically significant enough to to reject the null hypothesis. So
