PilotLPTM [1.2K]

Answer:

  D. The distance from the mean to an inflection point

Step-by-step explanation:

In fact, the inflection points are at x = ±1, where the curve changes from being concave downward to concave upward.

So, one standard deviation is the distance from the mean to an inflection point.
