The maximum number of sample defectives (c) for which this lot would be accepted for shipment without further inspection is determined by the acceptance quality level (AQL) or the indifference point, which in this case is 12% defectives. Given the small sample size of 15, the tolerance for defects is very low to ensure quality. Typically, a c=0 or c=1 defective acceptance criterion is used for small samples to maintain high quality standards. Since the question implies a willingness to accept a small number of defects rather than none (indicating some tolerance above zero defects), the best answer is 1 defective. This allows for a minimal level of defect while still aiming to maintain overall quality, aligning with the typical practices in quality control for small sample inspections.
