One-sided simultaneous lower prediction intervals are discussed, which contain at leastmi—ki+ 1 (i= 1, 2, ….l) out ofmiobservations inlfuture samples from a normal population. Such intervals are required, for example, when a manufacturer wishes to assure with a high probability the acceptance of alllfuture shipments of a product. The prediction limits are computed using the sample mean and the sample standard deviation of a past sample of sizenfrom the same normal population. Tables are provided for calculating such prediction limits when there are two future samples, and the procedure is illustrated by an example.
