To determine which inference can be drawn from the data, let's analyze the production numbers of each company.

Paper Giant:

  • 653
  • 647
  • 651
  • 658
  • 655

Wipe It Clean:

  • 756
  • 582
  • 734
  • 542
  • 784
  1. A. The workers at Wipe It Clean are more consistent than the workers at Paper Giant.

    • To assess consistency, we can calculate the range or the standard deviation. Wipe It Clean's production numbers vary significantly (highest 784, lowest 542), suggesting less consistency compared to Paper Giant.
  2. B. Wipe It Clean shows a wider variation in the numbers of paper towels produced than Paper Giant.

    • Calculating ranges:
      • Paper Giant: Range = 658 - 647 = 11
      • Wipe It Clean: Range = 784 - 542 = 242
    • Wipe It Clean shows much wider variation.
  3. C. On average, Paper Giant produces more paper towels than Wipe It Clean.

    • Calculate the averages:
      • Paper Giant average = (653 + 647 + 651 + 658 + 655) / 5 = 664
      • Wipe It Clean average = (756 + 582 + 734 + 542 + 784) / 5 = 679.6
    • This indicates that Paper Giant does not produce more on average.
  4. D. The data for Paper Giant has a higher median than the data for Wipe It Clean.

    • Find the medians:
      • Paper Giant sorted: 647, 651, 653, 655, 658 → Median = 653
      • Wipe It Clean sorted: 542, 582, 734, 756, 784 → Median = 734
    • This shows that the median of Wipe It Clean is higher.

Based on this analysis, the correct inference is:

B. Wipe It Clean shows a wider variation in the numbers of paper towels produced than Paper Giant.
