Question

Define the value of the mean, standard deviation, and variance in a standard normal distribution. the standard deviation of any standard normal distribution is____.

a.) 0.5
b.) 1
c.) 2
d.) 0

Answer 1

The mean of a standard normal distribution is 0, and the standard deviation is 1. So the correct answer is Option B.

Step-by-step explanation:

The standard normal distribution is a type of normal distribution with a mean of 0 and a standard deviation of 1. In this distribution, the mean represents the center of the distribution, while the standard deviation measures the spread or variability of the data. The variance is the square of the standard deviation.

In the standard normal distribution, the mean is 0 because the distribution is centered around 0. The standard deviation is 1 because it measures the average distance of each data point from the mean, and in the standard normal distribution, this average distance is 1.
