What is the meaning behind critical values? Like if I have a confidence interval of 95 (in which the z-score in 1.96) and I have a value that is say 2.30.. what would this mean in relationship to the confidence interval of 95?

Assuming that the value is a Z-score, and it is a two-tailed test, p < .05
