GATE 2024 ST – Question 63

Testing of Hypotheses · Likelihood Ratio and Large Sample Tests · 2 marks · Numerical answer

Four iid uniform(0,θ) observations test H₀:θ=1 against H₁:θ=.1 by rejecting if their maximum is below .3. If p is the Type-I error probability, find 100p to two decimals.

Show answer and explanation

Correct answer: 0.79 to 0.83

Explanation

Under H₀, each observation is below .3 with probability .3. Independence gives p=.3⁴=.0081. Hence **100p=.81**.
