Defective Aspirin Tablets The Acton Pharmaceutical Company manufactures aspirin tablets that are supposed to contain 325 mg of aspirin. Each day, 100 tablets are randomly selected and the amount of aspirin is measured. A tablet is considered defective if it has obvious physical deformities or the amount of aspirin is not between 315 mg and 335 mg. The numbers of defects are listed below for consecutive production days. Construct an appropriate control chart and determine whether the process is within statistical control. If not, identify which criteria lead to rejection of statistical stability.
