Quizplus · Accepted Answer

A z score of greater than 2 (or less than -2) is generally considered extreme and indicates a true difference between groups. A z score of less than 5% corresponds to a p-value of less than 0.05, which is commonly used as the cutoff for statistical significance in many fields. Therefore, option B (<5%) is the best answer as it indicates an extreme z score.
