To find the area above a positive Z score or below a negative Z score, we need to use the "Area Beyond Z" column of the Z score table. This column provides the area beyond a particular Z score, which includes the area above a positive Z score and below a negative Z score. We cannot use Option A since we do not subtract the Z score from the mean to find the area beyond it. Option C is incorrect as well since adding the Z score value to the area beyond the mean does not provide the desired area. Option D is also incorrect since adding the area between the Z score and the mean to 100% is not needed to find the desired area.
