Use Estimation Test Plan to determine the sample size necessary to estimate a percentile or reliability with a specified amount of precision.
Estimation test plans are similar to classical sample-size problems, but computations are more intensive because the data are usually censored. Estimation test plans allow for right- or interval-censored data.
You are developing a new type of insulation and want to determine the sample sizes necessary to estimate the 10th percentile with the distance from the lower bound to the estimate to be within 100, 200, and 300 hours. To do this estimation, you will run tests on small specimens for 1000 hours.
You have the following planning information:
