Question: A company uses the following acceptance sampling procedure A sample equal
A company uses the following acceptance-sampling procedure. A sample equal to 10% of the lot is taken. If 2% or less of the items in the sample are defective, the lot is accepted; otherwise, it is rejected. If submitted lots vary in size from 5,000 to 10,000 units, what can you say about the protection by this plan? If 0.05 is the desired LPD, does this scheme offer reasonable protection to the consumer?

Specifically, which runs would be made in each block? Consider the following 10 observations on time to failure: 50, 191, 63, 174, 71, 62, 119, 89, 123, and 175. Is either the exponential or the Weibull a reasonable choice of the time to failure distribution?
