  1. A packaging line's OEE (Overall Equipment Effectiveness) is calculated as 65%. If availability is 85% and performance is 90%, what is the quality rate?

    Answer: 84.8%

    OEE = Availability × Performance × Quality, so Quality = OEE ÷ (Availability × Performance) = 0.65 ÷ (0.85 × 0.90) = 0.848 or approximately 84.8%.

  2. When benchmarking packaging costs against industry peers, which data source provides the MOST reliable comparison?

    Answer: Published industry association benchmarking studies

    Industry association benchmarking studies aggregate data from multiple companies using standardized metrics, providing the most objective and comparable external reference.

  3. A corrugated box compression test yields these results across 10 samples (lbs): 285, 290, 278, 295, 288, 292, 301, 275, 289, 287. Which measure of central tendency BEST represents typical box strength?

    Answer: Mean

    The mean (arithmetic average) best represents the central tendency of a continuous measurement dataset without extreme outliers, as is the case here.

  4. A packaging sustainability report must calculate the carbon footprint per unit. Which data is ESSENTIAL for this calculation?

    Answer: Weight and material composition of packaging components plus transportation distances

    Carbon footprint calculations require material-specific emission factors applied to quantities used, plus transportation-related emissions based on mode and distance.

  5. In statistical acceptance sampling, increasing the Acceptance Quality Level (AQL) from 1.0 to 2.5 means:

    Answer: A higher defect rate is tolerated before rejecting a lot

    AQL represents the maximum acceptable defect percentage; a higher AQL number means the sampling plan tolerates a greater proportion of defective items.

  6. A packaging cost analysis shows total cost per unit decreased from $0.85 to $0.72 after a design change. What is the percentage cost reduction?

    Answer: 15.3%

    Percentage reduction = (0.85 - 0.72) / 0.85 × 100 = 0.13 / 0.85 × 100 = 15.3%.

  7. Which type of data collection tool would be MOST appropriate for tracking the frequency of five different defect types on a packaging line in real time?

    Answer: Check sheet

    A check sheet is a simple structured form designed for real-time manual tallying of defect types or events as they occur on the production floor.
