# Question: Consider a modified control chart with center line at

Consider a modified control chart with center line at µ = 0 and σ = 1.0 (known). If n = 5, the tolerable fraction nonconforming = 0.00135, and the control limits are at three-sigma, sketch the OC curve for the chart. On the same set of axes sketch the OC curve corresponding to the chart with two-sigma limits.

= 0, = 1.0, n = 5, = 0.00135, Z = Z0.00135 =

3.00 For 3-sigma limits, Z = 3

= 0, = 1.0, n = 5, = 0.00135, Z = Z0.00135 =

3.00 For 3-sigma limits, Z = 3
