(Statistical Process Control)

A wood shop produces processed wood chips with high precision. The shop wants to know whether the process is still controlled using statistical process control methods. The shop owner measured the length with 5 samples every day for 10 consecutive days according to the results in the table below.

Day	Sample 1	Sample 2	Sample 3	Sample 4	Sample 5
1	174	147	145	141	144
2	139	134	135	135	174
3	135	150	130	174	143
4	142	136	145	141	133
5	142	132	146	134	149
6	143	143	141	145	144
7	134	174	144	141	144
8	133	139	146	140	145
9	140	135	135	133	174
10	136	132	130	174	145

From the data above, the shop owner asks you as a quality expert to determine whether the production process is still under control with regard to quality.

Calculate LCL-X and UCL-X from these measurements and make a sketch of the X-Chart
Calculate the LCL-R and UCL-R from these measurements and make a sketch of the R-Chart
Analyze whether the process is still controlled or not. Explain your reasons.
