P value that is less than 0.05, that is P < 0.05 means that the null hypothesis is false and should be rejected. If the P value is greater than 0.05, that is P > 0.05, it means the null hypothesis is true. The P value is also called the calculated probability value. P value subtracted from 1 is the probability that the alternative hypothesis is true.
