Control Chart for X and R are kept on the weight in kilograms of a colour pigment for a batch process. After 25 subgroups with subgroup size of 4.
\( \sum \overline{x}=52.08 \ kg \\ \sum R=11.82 \)
Assuming process is in state of control, Compute the X and R chart central line and control limits.
(For subgroup size of 4, A2=0.729 D4=2.282 D3=0 d2=2.059).
