D) None of these choices.
Population Variance
The average of the squared differences from the Mean, for the entire population.
Zα/2
The z-score that corresponds to the critical value for a two-tailed hypothesis test at a given significance level α.
Maximum Allowable Error
The largest error or deviation from a standard or expected value that is considered acceptable.
