Question
Solution 1
The z-score is calculated by subtracting the mean from the individual score and then dividing by the standard deviation.
In this case, Joe's score is 25, the mean is 20, and the standard deviation is 5.
So, the z-score would be (25-20)/5 = 1.00. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowee AI StudyGPT is a powerful AI-powere
