N = 900 n = 89 c = 3 p = 00.4
A company uses the following acceptance-single sampling procedure.A sample of size n from the lot of N
items is taken and inspected.If c or less of the items in the sample are defective,the lot is accepted; otherwise,it is rejected.
a) Assume that the quality level(lot fraction defective) is p.What is the probability of acceptance P
of an incoming lot?
b) Consider annually 200 lots coming from the supplier.With application of this sampling procedure
and the given quality level p,what is the annual expected number of rejected lots?
c) Estimate Average Ongoing Quality for the given sampling procedure. d Estimate Average Total Inspection for the given sampling procedure.
The values specific to your student number for N,n,c and p are given in the additional tables.
