1. The problem statement, all variables and given/known data Find the expected value of a continuous variable y with pdf fy= alpha*y^-2, 0<y<infinity. I know it is the integral from zero to infinity of y*fy, but I don't know where to go from there. I'm then supposed to use the expected value to find the method of moments estimator. Does this pdf fall under a certain type of distribution? Any help is appreciated.
