Question

If a normal random variable has a mean = _____ and a standard deviation = _____, it is called a standard normal distribution.group of answer choices

Answer 1

If a normal random variable has mean of 0 and standard deviation of 1, it is called a standard normal distribution.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

• The z-score measures how many standard deviations the measure is above or below the mean.

• Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

For the standard normal distribution, the mean and the standard deviation are given, respectively, by:

$\mu = 0, \sigma = 1$
