Recall the definition of the standard normal distribution: it is a special case of the normal distribution with a specific mean and standard deviation.
The mean (\( \mu \)) of the standard normal distribution is always 0. This centers the distribution at zero on the horizontal axis.
The standard deviation (\( \sigma \)) of the standard normal distribution is always 1. This controls the spread or dispersion of the distribution around the mean.
Therefore, the standard normal distribution is denoted as \( N(0, 1) \), where 0 is the mean and 1 is the standard deviation.
Compare the given options to this definition to identify the correct mean and standard deviation for the standard normal distribution.
