मान लीजिए कि X, प्रायिकता घनत्व फलन (probability density function) f(x|θ) = 3/θ3(θ - x)2, यदि 0 < x < θ, और अन्यथा 0, से आकार 1 का एक यादृच्छिक प्रतिदर्श (random sample) है। यदि (x/(1 - λ1), x/(1 - λ2)) विश्वास्यता गुणांक 1 - α के साथ θ के लिए एक विश्वास्यता अंतराल (confidence interval) है, जहाँ λi ∈ (0,1), i = 1,2, λ1 < λ2, और α ∈ (0, 1) है, तो निम्नलिखित में से कौन सा कथन सत्य है?
- 1λ22 - λ12 = 1 - α
- 2λ23 - λ13 = 1 - α✓
- 3λ22 - λ12 = 4(1 - α)
- 4λ23 - λ13 = 9(1 - α)
सही उत्तर देखें
λ23 - λ13 = 1 - α
