2. Let X1, ... , Xn~ be iid for an exponential distribution with CDF Fe(x) = 1- e-x/0, for x > 0 and 0 > 0. The goal is to estimate the unknown 0. But suppose that, instead of observing X1, ... , Xn exactly, you only get to see whether or not each X; is greater than 7 or not. That is, you only observe Y1, ... ,Yn, where i, if X; > 7 Yi = 0, if X; 0 and 0 > 0. The goal is to estimate the unknown 0.
