can anyone help with this question pleaseeeee!!!!

b. Let X,, X, ,..., X, be a random sample from an exponential distribution with density function f ( * 10 ) = - e- 40 * > 0 (i) Determine the Fisher Information in a random sample of size n . (State the method used). ..... [7] (ii) Given that X is unbiased for 0, show that X achieves the Cramer-Rao lower bound for unbiased estimates of 0 . What then can we deduce about X? [5]
