The Normal Distribution, Revisited Practice Test

The area between 450 and 550 is less than the area between 400 and 600 because the first interval is closer to the mean.

The area between 400 and 500 equals the area between 500 and 600 because the intervals are symmetric about 500.

The area between 300 and 500 equals the area between 500 and 700 because the curve is taller on the left side.

The area between 400 and 500 is greater than the area between 500 and 600 because 400 is farther from the mean.

The area below 400 equals the area above 600 because both are within one standard deviation of the mean.
