A. Directions:
Read the following statements carefully.

Write ND if the statement describes a characteristic of a normal distribution, and NND if it does not
describe a characteristic of a normal distribution. Write your answers on a separate sheet of paper.

1. The curve of the distribution is bell-shaped.

2. In a normal distribution, the mean, median and mode are of equal values.

3. The normal curve gradually gets closer and closer to 0 on one side.

4. The curve is symmetrical about the mean.

5. The distance between the two inflection points of the normal curve is equal to the value of the mean.

6. A normal distribution has a mean that is also equal to the standard deviation.

7. The two parameters of the normal distribution are the mean and the standard deviation.

8. The normal curve can be described as asymptotic.

9. Two standard deviations away from the left and right of the mean is equal to 68.3%.

10. The area under the curve bounded by the x-axis is equal to 1.
