OPS MGMT – Two assembly lines making the same item are monitored

Two assembly lines making the same item are monitored, one with an X-bar chart and s chart combination and the other with an X-bar chart and R chart combination. The first assembly line has =108.4 and =2.21 based on subgroups of size 4. The second assembly line has =109.2 and =4.19 based on subgroups of size 5.1) Which assembly line exhibits more consistency (less spread)? Support your answer statistically. (5 pts)2) Calculate the control limits for the X-bar and s chart for assembly line 1. (5 pts)3) Calculate the control limits for the X-bar and R chart for assembly line 2. (5 pts)
