The image you've uploaded appears to be a question asking to find the mean, median, and mode of a frequency distribution. Here's the breakdown of the information given:

• Class Intervals:

  • 60-69
  • 55-59
  • 45-49
  • 40-49
  • 30-39

• Frequencies (fr):

  • 1
  • 4
  • 3
  • 7
  • 8
  • 6
  • 5
  • 3

I can now calculate the mean, median, and mode for this distribution. Would you like me to proceed with the calculation and provide explanations for each step?
