What’s In

Let us review your lesson on the properties of z-distribution. Write “YES” if the

statement is true about the z-distribution and “NO” if it’s not. Then check your

answer by going back to the previous module on z-distribution.

__________1. The z-distribution is a normal distribution with a mean of 0 and

standard deviation of 1.

__________2. The normal curve is bell-shaped.

__________3. The tails of the normal curve approach the vertical axis but never

touch it.

__________4. The mean is always greater than either the median or the mode.

__________5. The curve is symmetrical about its center.

__________6. The total area under the normal curve is always less than 1.

__________7. The mean, median and mode coincide at the center.

__________8. The width of the normal curve depends on the standard deviation of

the distribution.

__________9. Almost 99.7% of the distribution falls within three standard deviations

from the mean.

__________10. The left tail of the normal curve is flatter than its right tail.
