Question

what is the mean of the normal distribution shown below?
(graph of a normal distribution curve with x-axis labeled 0,1,2,3,4,5,6,7,8 and the peak at 4)
options: 0, 2, 4, 5

Explanation:

Step1: Recall Normal Distribution Property

In a normal distribution, the mean, median, and mode are equal and located at the center (peak) of the bell - shaped curve.

Step2: Identify the Peak's Position

Looking at the given normal distribution graph, the peak (highest point) of the curve is above the value 4 on the x - axis. Since the mean of a normal distribution is at the center (where the peak is), the mean should be 4.

Answer:

4
