It is to deny the strength of the original hypothesis, and the principle of p value is like this.

The overall hypothesis is the original hypothesis, so take a sample. Under the original assumption, the probability value of this sample appeared. According to the principle that small probability events cannot occur in experiments, P value is the probability value of small probability events (small probability events that reject the original hypothesis). The smaller the value, the less likely the original hypothesis is, which can also be called the significance level of rejecting the original hypothesis.
