摘要:A confidence interval is associated with a specified probability that the interval contains the true mean. A tolerance interval is associated with a specified probability that the interval contains a fixed proportion or more of the population values.

Tables for computing interval factors are given and an interesting relationship between the 2 intervals is established.

摘要:In biological work life testing may refer to expts. in which a group of animals is exposed to some stimulus (irradiation, drugs, etc.) and the time required for each animal to attain a certain response (death, a physiological threshold, etc.) is recorded. The authors discuss methods for estimating mean response times in which response times for only r out of n animals in a group are required. They show that for certain distributions, estimates based on r out of n response times are just as acc...
