Suppose that X follows a distribution with probability density function f θ (x) ∝ x θ-1 (1 - x) θ-1 ; 0 < x < 1, θ > 0. The uniformly most powerful critical region for testing H 0 : θ = 1 against H 1 : θ > 1 based on a single observation is of the form:
- 1[0, α 2 ) ∪ (1 - α 2 , 1]✓
- 21 - α 2 , 1 + α 2
- 3[0, α)
- 4(1 - α, 1]
Correct answer
[0, α 2 ) ∪ (1 - α 2 , 1]
