I thought that Chebychev's inequality is what would be used to solve this question, but the exceeding instead of the or more throws me off. Here is the question from Jim Pitman's book (I am studying for my final...)
Suppose the IQ scores of million individuals have a mean of 100 and a SD of 10.
Without making any further assumptions about the distribution of the scores, find an upper bound on the number of scores exceeding 130.
Thank You. No need for the answer, just I need to know whose inequality/theorem should I use. Though if someone can kindly explain Chebychev's theorem in detail, it would be awesome. He makes no sense.
