Wang Peng-de · Dali Xueyuan xuebao · 2007
This text mainly analyzed the confidence interval of the ratio of the two normal random variables and obtained the optimized one and proved its existence and uniqueness.The main result was that the first parameter and the second one had significant different effects on the optimized confidence interval,and this result enriched the application of the knowledge and developed a more accurate way.
