A CQPA-certified analyst notices that a colleague is rounding inspection measurements down to bring nonconforming parts within specification before submitting the data to the customer. The analyst's manager asks the team to "let it go this quarter" because of pressure to meet shipment targets. According to the ASQ Code of Ethics, the analyst should:
Correct answer: B - Report the data falsification through appropriate internal channels

Correct answer: C - Analyze
A process has a mean of 102, a standard deviation of 2, and specification limits of LSL = 94 and USL = 106. Calculate Cpk.
Correct answer: A - 0.67
An X̄ control chart shows the following pattern: 9 consecutive points all falling on the same side of the centerline, but all within the control limits. Which of the following is the correct interpretation?
Correct answer: B - A special cause is likely present, indicating a shift in the process mean
A factory produces parts on two independent production lines. The probability that Line A produces a defect is 0.05, and the probability that Line B produces a defect is 0.03. If one part is randomly selected from each line, what is the probability that BOTH parts are defective?
Correct answer: A - 0.0015
A quality team needs to perform acceptance sampling on incoming shipments of metal rods for which a critical-to-quality characteristic is the rod diameter, measured in millimeters. Which sampling standard is MOST appropriate?

A medical device manufacturer has just completed testing to confirm that their new infusion pump meets all of the engineering specifications listed in the design requirements document. Before releasing the device to market, regulators require an additional study to confirm that the pump actually meets the needs of clinicians and patients in real-world hospital environments. The first activity is BEST described as ___, and the second is BEST described as ___.
Correct answer: A - verification; validation
A team conducting an FMEA on a fuel injection assembly assigns the following ratings to a potential failure mode: Severity = 8, Occurrence = 4, Detection = 7. After implementing a new automated inspection step, Detection is reduced to 2 while Severity and Occurrence remain unchanged.
