# Question Suppose that Y1, Y2, ... ,Yn constitute a random sample from the density function п ? f(yle= {*)220 e-(y=0), y>0, elsewhere, = 10, where 0 is an unknown, positive constant. a) Find an estimator ê, for by the method of moments. (b) Find an estimator ôz for @ by the method of maximum likelihood. (c) Adjust ô7 and 62 so that they are unbiased. Find the efficiency of the adjusted ôn relative to the adjusted ô2.
