A)quotient obtained by dividing the larger Z score by the smaller.
B)product obtained by multiplying the smaller Z score by the larger Z score.
C)difference between the areas beyond each Z score.
D)sum of the areas associated with each Z score.

The proportion of the area under the normal curve between two Z scores that are both above the mean is found by calculating the difference between the areas beyond each Z score. This is because each Z score corresponds to a specific area to the right of it under the normal curve, and subtracting these areas gives the area between the two Z scores.
