Better Thаn Glаss Plаstics, a prоducer оf plastic bоttles, has recently implemented a statistical process control method. Four bottles are randomly selected and the diameter of the bottle neck is measured to make sure that the cap will seal appropriately. The accompanying table shows the dimensions in inches from the last six samples.
