A production process for the JMF Semicon is monitored using x-bar and R charts. 10 samples of n-15 observations have been gathered with the following results: Sample Mean Range 251 29 258 45 3. 233 36 275 25 234 35 6. 289 20 7. 256 3 265 19 246 14 10 323 46 Calculate the center line (CL), upper control limit (UCL), and lower control limit (LCL) for x-bar and R charts, and then draw the conclusion about whether the process is in control or not.
