# Question

A production line assembles electric clocks. The average number of nonconformities per clock is estimated to be 0.75. The quality engineer wishes to establish a c chart for this operation, using an inspection unit of six clocks. Find the three-sigma limits for this chart.

1 inspection unit = 6 clocks u = 075, nonconformities/clock

1 inspection unit = 6 clocks u = 075, nonconformities/clock
