Question 1

A small ________ can be disregarded in AOQ calculations involving an extremely large lot size.

Accepted Answer

The answer of A small ________ can be disregarded in...

Question 2

A single-sampling plan by attributes is needed for a purchased component. Table G.1 is appended to this exam.
Sample size = 80
Acceptance number (c) = 1
Acceptance quality level (AQL) = 0.02
Lot tolerance proportion defective (LTPD) = 0.06
Given the preceding information draw the AOQ curve and determine the AOQL.

Accepted Answer

The answer of A single-sampling plan by attributes is needed...

Question 3

A lot of 2,000 items has just arrived. A single sampling calls for a sample size of 100 and c = 3. What is the average outgoing quality limit, assuming that all defectives in the entire lot are replaced if it is rejected and all defectives are replaced in the sample if it is accepted? Table G.1 is appended to this exam.
A) less than or equal to 0.0150
B) greater than 0.0150 but less than or equal to 0.0175
C) greater than 0.0175 but less than or equal to 0.0200
D) greater than 0.0200

Accepted Answer

The average outgoing quality limit (AOQL) is calculated based on the sample size, acceptance number, and lot size. Given the parameters, the AOQL falls within the range greater than 0.0175 but less than or equal to 0.0200.

Question 4

The AOQ is often lower for a supplier with a high fraction defective than for a supplier with a comparatively lower fraction defective. Why wouldn't a supplier with a lower fraction defective always have a better AOQ?

Accepted Answer

The answer of The AOQ is often lower for a...

Question 5

Question 6

The maximum value of the average outgoing quality over all possible values of the proportion defective is called the ________.

Accepted Answer

Question 7

This OC curve represents a single sampling plan conducted on a lot size of 200 with a sample size of 20 and an acceptance number of 1. The y-coordinates of the first few points have been labeled; the x coordinates appear on the x-axis. If the receiving company uses rectified inspection, what is the greatest fraction defective that will enter their production process?

Accepted Answer

The answer of This OC curve represents a single sampling...
