The curve of a normal distribution extends indefinitely at the tails. 3. The area under the normal curve is 100. 4. The standard normal distribution is also called normal curve. 5. The mean of a standard normal curve is 3. 6. A small part of the area under the normal curve is found at the tails of the distribution. 7.
