Please help with the following problems involving normal distribution and populations.
Based off the three requirements that must be met before an analysis of variance test (ANOVA) can be used:
1. Samples must be randomly selected from the populations to be evaluated.
2. All populations from which the samples are selected must have a normal probability distribution.
3. All the populations from which samples are selected must have the same variance.

Problem: How might one know if the samples follow a normal distribution?
This distribution, with its symmetrical "bell-shaped" density curve is of fundamental importance in both statistical theory and practice. Its roles include the following
(i) it is a good model for ...
This posting helps with a problem involving normal distribution and populations. The solution examines normal distribution and populations using an ANOVA test. It is determined if the populations are normally distributed.
