Answer #1

1.

The normal distribution is the most important probability distribution in statistics because it fits many natural phenomena. For example, heights, blood pressure, measurement error, and IQ scores follow the normal distribution.

The normal distribution is the most important probability distribution in statistics because many continuous data in nature and psychology displays this bell-shaped curve when compiled and graphed.

(2). normally distributed means that if data are drawn (come from) a population that has a normal distribution.

When data are normally distributed, plotting them on a graph results a bell-shaped and symmetrical image often called the bell curve.
