question 4 of 10
which statement does not describe a normal distribution?
a. the distribution is symmetric.
b. most of the observations are near the mean.
c. the number of observations trails off as you move away from the mean.
d. the median may differ from the mean.

Explanation:

Step1: Recall the properties of a normal distribution

A normal distribution is symmetric about the mean.

Step2: Analyze the location of observations

Most of the observations in a normal distribution are near the mean and the number of observations trails off as you move away from the mean.

Step3: Check the relationship between mean and median

In a normal distribution, the mean, median and mode are all equal.

Answer:

D. The median may differ from the mean.
