Market Efficiency, business and finance homework help

In this paper, I want you to reference 3 outside sources. There are HUNDREDS, so I would not imagine that any of you would have the same reference. In this paper, I want you to find information and write up a short paper on: what market efficiency means, what it means for large institutional investors attempt to beat the market, and why this influences the way that small investors tend to invest. I also want to you find reference sources to discuss whether markets are indeed efficient or is this simply not possible.

The paper should be 3 pages and length and on the 4th page, list your references. I do not require a formal citation format, simply give me the source of you information.
