What is the total area under the normal curve?

• 1

• 2

• 3

• 0

The word asymptotic comes from a Greek word meaning

• gets closer and closer then intersect

• get closer and closer but never intersect

• mirror image

• not mirror image

Where is the skewness of the curve if the scores in a test are high?

• up

• down

• right

• left

The following are characteristics of a normal curve EXCEPT

• asymptotic to the x-axis

• symmetrical to the mean

• the total area is 1

• the mean, median and the mode are not equal
