Suppose that X₁, X₂, ..., Xn form a random sample from the

exponential distribution with parameter X, i.e.,

f(x; X) = {

\e-\x, x>0

0, x < 0

de-Ar

(a)Using the method of moment to estimate parameter X based

on sample of size n.

(b)Using the method of maximum likelihood to estimate

parameter based on sample of size n.
