Answer 1

The correct response is: When graphed, the data creates a bell curve.

In a normal distribution, when the data is plotted, it will typically form a bell-shaped curve, indicating that most observations cluster around the mean with fewer observations at the extremes. This is a key characteristic of normal distributions.
