1. The problem asks to find the median of the data given in class intervals with frequencies. 2. The class intervals are: 5-9, 10-14, 15-19, 20-24, 25-29, 30-34, but the frequency values are missing (except for a note "Taken from Yr roll No."). 3. To find the median, we need the frequency data to calculate cumulative frequencies and identify the median class. 4. Without the frequency values, finding the median is impossible. 5. Please provide the frequency values associated with each class interval to proceed with calculating the median.
