Compute the median for the following cumulative frequency distribution:

Explanation

As,we are given the cumulative frequency distribution.

So, we first construct a frequency table from the given cumulative frequency distribution

`[[Class ,Frequency (f) , (c.f.)],[
20-30 ,4 ,4
],[30-40, 12 ,16],[
40-50 ,14, 30],[
50-60 ,16, 46],[
60-70, 20, 66],[
