Let X1, X2, X3, X4 be independent and identically distributed (i.i.d.) random variables having a Uniform distribution on (0, θ) where θ > 0 is an unknown parameter. Define X(4) = max{X1, X2, X3, X4}. Consider the confidence intervals I = [2X(4), 3X(4)] and J = [X(4), 1 + X(4)) for θ. Which of the following is true?

- 1The coverage probabilities of I and J are both independent of θ.
- 2The coverage probability of I is independent of θ but the coverage probability of J is NOT independent of θ.✓
- 3The coverage probability of J is independent of θ but the coverage probability of I is NOT independent of θ.
- 4The coverage probabilities of both I and J are NOT independent o f θ.
Correct answer
The coverage probability of I is independent of θ but the coverage probability of J is NOT independent of θ.
