A random sample of 200 units will be inspected each day for nonconforming units. Data for the last 10 days is given below. Day 1 2 3 4 5 6 7 8 9 10 Average # Units 200 200 200 200 200 200 200 200 200 200 200 # Nonconforming Units 4 0 2 3 4 3 5 3 9 3 3.6 % Nonconforming 2.0% 0.0% 1.0% 1.5% 2.0% 1.5% 2.5% 1.5% 4.5% 1.5% 1.8% As the team's SPC expert, which control chart would you recommend?
