Question 17134d4d

Problem-Solving and Data Analysis - One-variable data: Distributions and measures of center and spread

  • Company A: 
    • The horizontal axis is labeled Number of units sold (in thousands). It ranges from 15 to 50 and is divided into 7 equal intervals. 
    • The vertical axis is labeled Frequency. It ranges from 0 to 50. 
    • The histogram has 3 bins. 
    • The Frequency data for the 3 bins are as follows:
      • 25 to 29: 43
      • 30 to 34: 48
      • 35 to 39: 43
  • Company B:
    • The horizontal axis is labeled Number of units sold (in thousands). It ranges from 15 to 50 and is divided into 7 equal intervals. 
    • The vertical axis is labeled Frequency. It ranges from 0 to 50. 
    • The histogram has 7 bins.
    • The Frequency data for the 7 bins are as follows:
      • 15 to 19: 31
      • 20 to 24: 24
      • 25 to 29: 11
      • 30 to 34: 3
      • 35 to 39: 11
      • 40 to 44: 24
      • 45 to 49: 31

The histograms summarize the distributions of number of units sold, in thousands, for company A and company B. Which statement best compares the standard deviations of number of units sold for these companies?
