The median of any Normal distribution is the same as its mean. We can use Normal calculations to find the quartiles for Normal distributions.

What is the area under the standard Normal curve to the left of the first quartile? Use this to find the value of the first quartile for a standard Normal distribution. Find the third quartile similarly.

**Solution: **The first quartile is -0.67499, and the area under the standard Normal curve to the left of the first quartile is 0.25. On the other hand, the third quartile is 0.67499, and the area under the standard Normal curve to the left of the third quartile is 0.75
