The following sampling plan has been established in a company. A size 2 sample is drawn if both items are ok the lot is accepted. Otherwise a second sample of size 1 is taken if that item from the second sample is ok the lot is accepted otherwise the lot is rejected. [5]
a) Develop a probability tree diagram to list the possible results of the first sample and the second sample. [15]
b) If the inspector receives a batch with 10% of items affected, calculate the probability of accepting that batch.
show steps clearly please. Good review.

The following sampling plan has been established in a company. A sample of size 2 if both items are good lot is accepted. Otherwise a second sample size 1 if that second sample item is good the otherwise the batch is rejected. a) Develop a probability tree diagram to list the possible outcomes of the first sample and the second sample. b) If the inspector receives a batch with 10% of damaged items, calculates the probability of accept that lot.

An acceptance sampling plan with and has been designed with a producer’s risk of .075. Was the value of .01, .02, .03, .04, or .05? What does this value mean?
