If the observed results are unlikely under the null hypothesis, your reject the null hypothesis.

3. ## p-value - Wikipedia

https://en.wikipedia.org/wiki/P-value

In statistical hypothesis testing, the p-value or probability value or asymptotic significance is the probability for a given statistical model that, when the null hypothesis is true, the statistical summary (such as the sample mean difference between two compared groups) would be greater than or equal to the actual observed results. The use of p-values in statistical hypothesis testing is ...
