Let {X i : 1 ≤ i ≤ 2n} be independently and identically distributed normal random variables with mean μ and variance 1, and independent of a standard Cauchy random variable W. Which of the following statistics is consistent for μ?
- 1n −1 (∑ i=1 n X i + W)✓
- 2n −1 ∑ i=1 n X 2i−1
- 3n −1 ∑ i=1 2n X i
- 4n −1 ∑ i=1 n X i
Correct answer
n −1 (∑ i=1 n X i + W)
