The tells us that for a population with any distribution

This is related to "Probability Theory" and specificaly reffers to "The Central Limit Theorem" which states that independently of what an original normal data looks like, the distribtion of the sample is aproximatelly normally distributed.

Thus for a  population with any distribution, as the sample size grows, the distribution of the sums for the sample means aproaches a normal distribution.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
