White Rock is trying to determine an acceptance sampling plan for parts Y500 and P2000, both of which are purchased from suppliers.

Part Y500 is purchased in lot sizes of 6000. Management has decided to adopt a single attribute-based sampling plan with a sample of 160 units and an acceptable number of 1. Management has also decided that the AQL and LTPD are 0.010 (1%) and 0.020 (2%), respectively.

Answer each of the following questions. For each question, use at least four decimal places when doing your calculations, but tin ROUND OFF your answer to the number of decimal places specified for each question.

-If there are 1% defectives in a shipment of Y500s, whull Is the probability of there being no defectives in a sample of 160 (round to 2 decimal pieces)?

-If there are 1% defectives in a shipment Y500s, what is the probability of there being exactly 1 defective in a sample of 160 (round to 2 decimal places)?

-What is the probability of a Type I error given the sampling pian for Y 500 found to 2 decimal places)?
