Answer:

It can not be find by this data

Step-by-step explanation:

Median is the middle observation of the given set of data.

Median of the grouped data is calculate by:

Estimated Median = L +   ((n÷2) − B) ÷ G  × w

where, L = lower class of the group containing the median

n = total number of frequencies.

B = cumulative frequency of the groups before the median group

G = frequency of the median group

w = group width
