If μ = 9 ounces, σ = 0.5 ounces, and n = 9, calculate the 3-sigma control limits.

Sigma Control Limits

Statistical boundaries set within a control chart to identify the acceptable range of process variations in Six Sigma methodologies.

Standard Deviation

A measure of the dispersion or variation in a set of values, indicating how spread out the values are from the average.

Lead in the calculation and expression of control limits and the capacity of processes within manifold control chart categories, including X-bar, R-chart, p-chart, and c-chart.
Apply 3-sigma rules for determining process control.
