Let X and Y be independentrandomvariableswith X Poissons dis-
tributedwithmean λ and Y exponentiallydistributedwithrate λ, where λ > 0, and let (X1, Y1), ..., (Xn, Yn) be asamplefromthisdistribution.
a) Determineamomentestimator ˜λn for λ based onthestatistic t(x, y) = x − y and thesample (X1, Y1), ..., (Xn, Yn) and finditsasymptoticdistribution.
b) FindtheasymptoticdistributionoftheMLE ˆλn of λ.
c) Comparetheasymptoticdistributionsoftheestimators ˜λn and˜λn.
