A random variable X follows the normal distribution, and another random variable Z follows the standard normal distribution
1) Explain the difference between the normal distribution and the standard distribution
---
The standard normal has a mean of zero and a standard deviation of one.
A normal distribution may have any number as mean and any number as
standard deviation.
-----------------------------
2) Explain how the variables, X and Z are related.
Te data in both cases is symmetric wrt the mean and
both have a range of approximately 6 standard deviations.
