IE 300 FINAL questions with verified
answers graded A+ to pass
Acceptance Sampling can be utilized for:
- Only Incoming inspection and verification
- Only Outgoing inspection and verification
- Development of control chart USL and LSL values
- Incoming and outgoing inspections - correct answer ✔✔Incoming and outgoing inspections
A customer may choose to use a 0% sampling plan (no-inspection) when:
- The supplier's process is so good that defective units are never experienced
- The supplier's process is so bad that almost every unit is defective
- The supplier is within the same company
- The component is extremely critical - correct answer ✔✔The supplier's process is so good that
defective units are never experienced
When is acceptance sampling not used?
- There is a need for continuous monitoring of process capability, even if the process is
consistently in control.
- Any tests/inspection to confirm acceptance are destructive.
- The cost of 100% inspection is not economically wise.
- The supplier's process is highly capable of producing acceptable parts. - correct answer
✔✔The supplier's process is highly capable of producing acceptable parts
, Can an acceptable, or 'good' lot be rejected through the use of acceptance sampling?
- Yes, this is called a Type 1 Error (or Producer's Risk), because the supplier or producer suffers
when a good lot is rejected, but should have been accepted.
- Yes, this is called a Type 2 Error (or Consumer's Risk), because the supplier or producer
accepted a lot, which should have been rejected, which negatively affect the Consumer.
- No, this is why we use Acceptance Sampling. - correct answer ✔✔Yes, this is called a Type 1
Error (or Producer's Risk), because the supplier or producer suffers when a good lot is rejected,
but should have been accepted.
What is an AQL?
- Appropriate Quality Limit
- Alpha Quality Level
- Acceptable Quality Level
- Average Quality Level - correct answer ✔✔Acceptable Quality Level
Why would an OC (Operating Characteristic) curve be useful?
- To determine tomorrow's weather patterns within a given amount of certainty.
- To assess the properties and effectiveness of a sampling plan.
- To determine the number of samples required for a particular sampling plan.
- To determine the correct sampling plan letter to use with Mil Std 105E. - correct answer ✔✔To
assess the properties and effectiveness of a sampling plan.
Given that larger lots are preferred for sampling, as they will give a better representation of a
population within a confidence level.
