Z-statistic

A measure that quantifies the difference between the observed value and the expected value under the null hypothesis, expressed in terms of standard deviations.

Do not Reject

A decision in hypothesis testing that indicates insufficient evidence to conclude the alternative hypothesis is true.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how much the values differ from the mean of the set.
