Uh, no, it is not safe to say that salaries are normally distributed, and they certainly aren't. The salary distribution graph for a large corporation is likely to look something like this: http://www.visier.com/wp-content/uploads/2016/05/Graph-showing-the-US-income-distribution-for-fully-employed-workers-who-are-newly-eligible-for-overtime-under-the-new-FLSA-rule.png http://www.visier.com/wp-content/uploads/2016/05/Graph-showi... with a very, very, very long tail to the right representing the salaries of the CEO and senior executives. Depending on the corporation, there may be multiple humps ("salaries for Amazon warehouse workers" representing one hump, and "salaries for Amazon programmers" representing another, for example). It's nothing like a normal curve.
