The p-chart is used to monitor the proportion of defectives in a sample. It is appropriate for this situation where the inspection is checking the fraction of defective products in a shipment from a supplier. The x-bar chart and R-chart are used to monitor the process mean and process variability, respectively, and are not appropriate for this situation. The c-chart is used to monitor the number of defects in a sample of a fixed size, and is also not appropriate for this situation where the sample size may vary.
