2 Suppose the distribution of some random variable X is modeled as uniform on (r, s). Find a closed-form expression for the MM, i.e., method of moments, estimator of r and s, based on data X1,...,X. 3 Consider the parametric density family ct-1 for t in (0, 1), 0 elsewhere. Find closed-form expres- sions for the MLE, i.e., maximum likelihood estimator, and the MM, i.e., method of moments, estimate, based on data X1,...,Xn.
