Argue that the proposed estimators πœ†Λ† and πœ†Λœ below are both consistent and asymptotically normal. Then, give their asymptotic variances 𝑉(πœ†Λ†) and 𝑉(πœ†Λœ) , and decide if one of them is always bigger than the other.

Let 𝑋1,…,π‘‹π‘›βˆΌπ‘–.𝑖.𝑑.π–―π—ˆπ—‚π—Œπ—Œ(πœ†) , for some πœ†>0 . Let πœ†Μ‚ =π‘‹βŽ―βŽ―βŽ―βŽ―βŽ―π‘› and πœ†Μƒ =βˆ’ln(π‘ŒβŽ―βŽ―βŽ―βŽ―π‘›) , where π‘Œπ‘–=1{𝑋𝑖=0},𝑖=1,…,𝑛 .

𝑉(πœ†Λ†) =? and 𝑉(πœ†Λœ) =?
