The correct response is:
**When graphed, the data creates a bell curve.**
A normal distribution is characterized by a bell-shaped curve when the data is graphed, indicating that most of the data points cluster around the mean and taper off symmetrically towards the extremes. If the statistician found that the height data creates this bell curve, they would conclude that it follows a normal distribution.
