Could you please help me with this question?

4. (25 points) Let X1,X2, ...,X2n_1 be iid Exponential (o), where ,u, > 0. (Note that there are an odd number of random variables.) Let A #1 = CX(n) and _ I32 =X where c is such that l is unbiased. (a) Find 0. (b) Find the Fisher Information based on a single random variable X1. (Work required) (6) Compute eff (I31). (Work required) (d) Compute eff (I22). (Work required) (e) Compute eff (I31, I32). (Work required)
