Let X₁, X₂.... 2022/05/2represent a random sample from a shifted exponential with pdf f(x; λ,0) = Ae-(-0); x ≥ 0, > where, from previous experience it is known that 0 = 0.64. a. Construct a maximum-likelihood estimator of A. b. If 10 independent samples are made, resulting in the values: 3.11, 0.64, 2.55, 2.20, 5.44, 3.42, 10.39, 8.93, 17.82, and 1.30 calculate the estimates of A.
