Jul3 comment Prove $\mu(\{|f-\mu f|>K\}) \le \frac{1}{K^2}(\mu f^2 -(\mu f)^2)$ Thanks! I was asked to prove/disprove the expression, so I guess it's false. Jul3 comment Prove $\mu(\{|f-\mu f|>K\}) \le \frac{1}{K^2}(\mu f^2 -(\mu f)^2)$ Thanks. Didnt realise the connection/relation to Chebychev's inequality.
