3. The width of the curve is determined by the___________of the distribution.

4. The curve is__________to the base line.

5. The area to the left of z = 0 (or to the right of z = 0) is_____________.

6. The curve is___________about its center.

7. The mean, median, and mode of the normal curve are_____________.

8. The area between z = 0 and z = 1 is _______________.

9. The table of areas under the normal curve is also called____________.

10.The standard normal curve is a normal probability distribution that has a mean

of_____________and standard deviation of_____________.

Answer 1

1. The distribution curve is a graph of probability distribution.

All Normal Curves have the same general bell shape.

2. The area under the curve is measure of the probability. The total area under the curve is equal to 1.

3. The width of the curve is determined by the standard deviation of the distribution.

4. The curve is approaching to the base line more and more closely as the distance from the mean increases. 

5. The area to the left of z = 0 (or to the right of z = 0) is 0.5.

6. The curve is symetric about its center.

7. The mean, median, and mode of the normal curve are equal.

8. The area between z = 0 and z = 1 is 0.341345.

9. The table of areas under the normal curve is also called z-score table.

10.The standard normal curve is a normal probability distribution that has a mean of zero and standard deviation of 1.
