What is a normal distribution? If you look at a process and can use a tool to normalize the data, or convert it to a normal distribution, how does that benefit the testing to ensure the process is working correctly?
(a) The normal distribution is a family of probability distributions of the same general form, but differing in their position and parameters. The parameters of the normal distribution are (a) The mean and (b) The standard deviation.
The standard normal distribution is the normal distribution with a mean of 0 and a variance of 1.
The main characteristics of the normal distribution are:
(1) The distribution is bell shaped
(2) The normal probability ...
