Increasing the sample size (n) will reduce the consumer's risk for a given Acceptable Quality Level (AQL) and Lot Tolerance Percent Defective (LTPD), as it increases the chances of finding defects if they exist in the lot. Keeping the consumer's risk constant by keeping the Lot Tolerance Percent Defective (LTPD) constant and increasing the sample size (n) is the best option. Increasing beta (Type II error rate) does not reduce the consumer's risk but, in fact, increases the risk of accepting the lot when it is actually defective. Reducing n and increasing c will increase the consumer's risk because it means accepting more defects in the lot.
