Both of your answers are incorrect. The appropriate control chart for this problem is the c-chart, which is used for controlling the number of defects when more than one defect can be present in a service or product. Use the formulas below to compute the upper and lower control limits for a c-chart, where c is the central line on the chart, which is equal to the mean of the distribution, Vc is the standard deviation, and z is the normal deviate (number of standard deviations from the average). UCL. =c+z/c and LCL, =c-zdc. OK
