Normal probability table (z-scores) and critical values of the chi-squared distribution. The normal probability table lists the probability of finding a z-score below a given value, while the chi-squared distribution critical values indicate the chi-square value required to achieve a specific level of significance. These tables are essential in statistical analysis, particularly in hypothesis testing and confidence interval estimation.
