Question

what is the mean of the normal distribution shown below? (there is a normal distribution curve and a number line with -3, -2, -1, 0, 1, 2, 3, and multiple - choice options: -1, 0, 1, 2)

Explanation:

Step1: Recall Normal Distribution Property

In a normal distribution, the mean (μ) 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 of the bell - curve (the center of symmetry) is at the value 0 on the x - axis. So, the mean of this normal distribution should be 0.

Answer:

0
