Section 14 – Acceptance Sampling Procedures UGA FDST 4090/6090 - (c) W.C. Hurst 2009 1 Acceptance Sampling Procedures William C. Hurst FDST 4090/6090 (2009) Acceptance Sampling • Statistical sampling procedure employed to FDST 4090/6090 © W.C. Hurst 2009 Considerations for Any Sampling Plan • Less information in sample • Represents • Risk of rejecting “good” lots (Type I error) and accepting “bad” lots (Type II FDST 4090/6090 © W.C. Hurst 2009 Represents error) Benefits of Acceptance Sampling FDST 4090/6090 © W.C. Hurst 2009 Single Sampling Plan • Suppose a fresh-cut processor receives a lot size of 10,000 lettuce heads from which he draws a random sample of 10 heads for inspection FDST 4090/6090 © W.C. Hurst 2009 for inspection. • He will reject the lot if he finds 2 or more defective heads and accept it if he finds 1 or fewer defective heads. • Develop a sampling plan for this problem. Calculating Single Sampling N = Lettuce heads in lot = n = Sample size = a = Acceptance batch number = FDST 4090/6090 © W.C. Hurst 2009 r = Rejection number = P A = Probability acceptance batch based on good sample p = Unknown proportion defectives in batch SEE WORKSHEET
