Exam 5: Supplement Operational Decision-Making Tools: Acceptance Sampling

With a single-sample attribute plan a single sample of size n is selected randomly from a larger lot and each of the n items is inspected.

The _________________ is the probability of rejecting a lot that has an acceptable quality level.

The ________________ is the consumer's willingness to accept lots with a small proportion of defective items

A sampling plan provides a set of guidelines for rejecting a lot.

The simplest form of a sampling plan is a double-sample attribute plan.

The operating characteristic (OC)curve __________.

The _________________ is the probability of accepting a lot that has a higher percentage of defective items than the lot tolerance percent defective.

A multiple-sampling plan uses the smallest sample size of any sampling plan.

The consumer's risk is the probability of accepting a lot in which the fraction of defective items exceeds the lot tolerance percent defective (LTPD).

A lot is rejected if the number of defective units found in a random sample exceeds a predetermined acceptable number of defective units.

With acceptance sampling,a lot is either rejected or accepted depending on the number of defects found in a sample.

A multiple-sampling plan __________.

The average outgoing quality (AOQ)is a measure of the expected number of defective items that will pass on to the customer with the sampling plan selected.

In a single-sample attribute plan,which of the following choices is true about the lot size (N),the sample size (n),the acceptable number of defective items in a sample (c),and the actual number of defective items in a sample (d)?

Double-sampling plans are often less costly than single-sampling plans.

The ______________________ is the expected number of defective items that will pass on to the customer with a sampling.

The consumer's risk is the probability of rejecting a lot that meets the acceptable quality level (AQL).

Choosing among a single-,double- and multiple-sampling plans is a strategic versus an economic decision.

Acceptance sampling is not consistent with TQM's philosophy of zero defects.

An operating characteristics (OC)curve is a graph that measures the probability of accepting a lot with no defective items.
