Question

A single-sampling plan has ? = 0.01, ? = 0.01, ?2 = 0.05, and ? = 0.02. What should be the sample size ? and acceptance number ??

Answer #1

Answer the following questions for a single sampling plan with
sample size n = 80 and c = 3
If AQL = 2% and LTPD = 7%, what would be the producer's and
consumer's risks associated with the sampling plan?

Suppose that a supplier ships components in lots of size 5000. A
single-sampling plan with n = 50 and
c = 2 is being used for receiving inspection. Rejected
lots are screened, and all defective items are
reworked and returned to the lot.
(a) Draw the OC curve for this plan.
(b) Find the level of lot quality that will be rejected 90% of
the time.
(c) Management has objected to the use of the above sampling
procedure and wants...

Acceptance Sampling: For the sampling plan defined by N=1500,
n=150, c=2
3. Develop the Operational Characteristics Curve. With this
plan, what is the probability of acceptance for a batch that
contains 2% non-conforming material?
4. Develop the Average Total Inspection curve. With this plan,
what is the average total inspection for batches that contain 2%
non-conforming material?

For a double-sampling plan with n1= 75 c1= 2 n2= 110 c2= 6 a.
Draw the OC curves (Probability of acceptance on first sample,
Probability of acceptance on combined samples, Probability of
rejection on first sample) (You must use a scatter plot)
b. If the incoming lots have fraction nonconforming p= 0,07

b.1. What is the probability of acceptance on the first sample?

b.2. What is the probability of final acceptance?
b.3. Calculate the probability of rejection on...

Describe the circumstances in which
the lot will be inspected to the third stage but will not proceed
to the fourth stage.

a) For c = 0. draw a sketch of three QC-curves on the same axes
showing what the effect is of sample size (n) on the probability of
acceptance for a single sampling plan. Depict three different
sample sizes of n1 > n2 > n 3 .
b) What is the effect of non the probability of acceptance?
c) Design a single sampling plan for the following scenario: i.
Lots with a fraction defective of 0,05 and an a of...

A sequential sampling plan is to be used. It is desirable to
have a producer's risk of 0.05 at AQL = 0.008 and a consumer's risk
of 0.07 at LQL = 0.082. Determine the equations for the acceptance
and rejection lines. What is the first opportunity to reject? What
is the first opportunity to accept?

(c) Draw the ATI curve for this plan.
(d) Find the level of lot quality that will be rejected 90% of
the time.
(e) Suppose that incoming lots...
