Consider X1, ..., Xn to be a random sample from the PDF 303 f(xx | 0) = ( 2 + 0 ) 4 ' x > 0, depending on the parameter 0 > 0. (a) Find the MOM estimator On for 0. (b) Find the bias and variance of On. (c) Find the Fisher Information from a single observation of 0. (d) Is the MOM On an efficient estimator? Does this result surprise you
