XbarS Chart Exercise
Data File: XbarS.MTW
A small and fairly new pharmaceutical company has an over-the-counter liquid drug product that has two shifts of production packaging bottles intended to contain 5 oz of medication. As the quality control engineer, you are tasked with monitoring the fill quantities within and between shifts using statistical process control. You have collected 25 samples per shift over the course of eight business days. Use the “XbarS.MTW” data file to run an XbarS chart on the 400 oz samples, with the subgroups being production shift. Determine if any out-of-control conditions exist.
