Answer

Explanation:

Step1: Analyze original and updated data

The original data has values like 7.5, 8.25, 9 etc. After update, 9 becomes 11 and 11.75 becomes 12.

Step2: Check each range

  • For 7.25 - 8: Original data has 7.5 which may affect frequency.
  • For 8.25 - 9: Original 8.25 is here, and change of 9 to 11 affects it.
  • For 9.25 - 10: No original values in this range are changed directly, but change of 9 to 11 might have indirect impact on count in adjacent - ranges which could affect this one.
  • For 10.25 - 11: Original 10.5, 10.75 etc. are here, and change of 9 to 11 and 11.75 to 12 can change overall distribution and thus frequency.
  • For 11.25 - 12: Change of 11.75 to 12 directly affects this range.

Answer:

7.25 - 8, 8.25 - 9, 9.25 - 10, 10.25 - 11, 11.25 - 12
