The mean of a Standard Normal Distribution is:

Question

BlackTom AI · Accepted Answer

The question asks about the mean of a Standard Normal Distribution. 
First, recall that a Standard Normal Distribution is a normal distribution with a mean of 0 and a standard deviation of 1; it is the standardized form N(0,1) used for z-scores and standardization.
Because the standardization process centers the distribution at zero, the location parameter (the mean) is 0 by definition. People often confuse the mean with the center of mass in samples, but for the standard normal, the theoretical mean is exactly 0.
In this problem, there are no answer choices provided to evaluate, so we cannot annotate each option. However, given the standard definition, any correct interpretation would align with the mean being 0.
Common misunderstandings include thinking the mean could be any other value or that the mean varies with sample, but for the standard normal, both the population mean and the distribution’s center are fixed at 0.
If you were to check typical multiple-choice structures, you’d expect an option like 0 to reflect the standard normal mean; other numbers would contradict the defining properties of N(0,1).
