Hello, I am stuck on this question as shown in the picture below:

(i) (2 points) Suppose X1, ..., Xn denote a random sample of size n from an exponential distribution with density function given by f (x ) = Soe-ex for x > 0 10, otherwise (a) Find the MLE of 0 (b) Find the MSE of OMLE- (Hint: if X1, ..., Xn from exponential distribution shown above, then X~I(n, no), ~Inverse - Gamma(n, no), which has mean ne and variance - (no) 2 n-1 (n-1)2(n-2)
