1. From the following $X$-bar and $R$ chart, where $n=3$, to conduct process capability analysis. The specifications are as follows: $12.7\pm 2.0\mathrm{cm}$. Use the space below the chart to show your work. a. Verify that the process is stable. How do you know? b. Calculate the relevant indices ( $\mathrm{Cp}$ and $\mathrm{Cpk}$ ) c. Is the process capable? Why or why not? d. Is the process centered? Why or why not?
