The p-value is the probability of obtaining test results at least as extreme as the results actually observed, under the assumption that the null hypothesis is correct. When the critical area is in the lower tail, the p-value corresponds to the area under the curve to the left of the test statistic, making it less than or equal to the test statistic.
