    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.

    How might one know if the samples follow a normal distribution?

    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
