Control chart. A laboratory monitoring perchlorate $\left(CI{O^{-}}_4\right)$in urine measured quality control samples made from synthetic urine spiked with$\mathit{C}\mathit{I}{{\mathit{O}}^{\mathbf{-}}}_{\mathbf{4}}$. The graph in Box$\mathbf{5}\mathbf{-}\mathbf{2}$shows consecutive quality control measurements. Are any troubleshooting conditions from Box 5-2 observed in these data?

A Control Chart is a visual representation of the confidence intervals for a Gaussian distribution.

Interpretation:

It is necessary to explain the troubleshooting conditions for a control chart that monitors perchlorate$\left(\mathrm{CI}{{\mathrm{O}}^{-}}_4\right)$in urine measured quality control samples made from synthetic urine spiked with.

Six signs that a process might be getting out of control.

1. Keen observation outside the action lines -No

2. There is always 2 out of 3 measurements between action and warning lines-No

3. There are all 7 consecutive measurements above or below the center line-Yes

4. There are all 6 measurements which can be increasing or decreasing where they are located-No

5. There are 14 points which are alternating up and down regardless where they are located-No

6. A nonrandom pattern-No
