5. The smallest defect in a computer chip will render the entire chip worthless. Therefore, tight quality control measures must be established to monitor these chips. In the past, the percentage of defective for these chips has been 3%. The sample size is 100 . Calculate the upper and lower control limits of a P-chart to monitor this process. Also determine whether the process is in 6. Cool Tecluolugies produces refrigeration units for food producers and retail food establishments.
