Is there something specific you’d like assistance with regarding the previous problem or another question? Let me know, and I’ll be glad to help!

If you'd like, here are some ways I can assist further:

1. Go over how to find the mean in a grouped frequency table.
2. Explain the difference between median, mean, and mode in grouped data.
3. Show steps to calculate the exact median if more detailed cumulative data were given.
4. Demonstrate how to graph cumulative frequency for visualizing data.
5. Clarify how changing class intervals might affect the median and interpretation.

Tip: For accuracy in statistics, understanding cumulative frequency tables can help in approximating not just medians, but also quartiles and other percentiles.
