Question

what is the mean of the normal distribution shown below? -3 -2 -1 0 1 2 3 -1 0 1 2

Explanation:

Step1: Recall Normal Distribution Property

In a normal distribution, the mean ($\mu$) is the center of the symmetric bell - shaped curve. The curve is symmetric about the mean.

Step2: Analyze the Graph

Looking at the given normal distribution graph, the peak (the highest point) of the bell - shaped curve is at the value 0 on the x - axis. Since the normal distribution is symmetric about the mean, and the peak occurs at $x = 0$, the mean of this normal distribution is 0.

Answer:

0 (corresponding to the option "0")
