Bottle fill volume bell curve

This bell curve shows a bottling line whose fill volumes cluster around the 500 ml target. A narrow, centered distribution suggests consistent filling, while a curve shifted away from the target or spread too widely can signal adjustment or maintenance needs. The values here are relative frequencies for a teaching example, not a compliance result. In a live quality review, use measured fill data, specify the sampling period and plot the actual tolerance limits. The curve then becomes a quick visual for discussing process centering, variation and the risk of fills outside specification. It gives teams a concrete starting point for reviewing assumptions, data quality and next steps together.
