The p-value is the probability of obtaining a test statistic as extreme or more extreme than the one observed in the sample, assuming the null hypothesis is true. In a two-tailed test, extreme values could be in either tail of the distribution, making it less likely to obtain such extreme values. Therefore, a low p-value indicates that the observed sample result is unlikely under the null hypothesis, and we reject the null hypothesis in favor of the alternative hypothesis.
