Why P=0.05? The standard level of significance used to justify a claim of a statistically significant effect is 0.05. For better or worse, the term statistically significant has become synonymous with P 0.05. There are many theories and stories to account for the use of P=0.05 to denote statistical significance.

Level of significance, or significance level, refers to a criterion of judgment upon which a decision is made regarding the value stated in a null hypothesis. The criterion is based on the probability of obtaining a statistic measured in a sample if the value stated in the null hypothesis were true.

At the 5% level of significance, H0 is rejected if Z is greater than the critical value of 1.645 or X is greater than 2(1. 645 )/ n.Note that the Z statistic is an increasing function of sample size or the critical value for X is a decreasing function of sample size.
