Step-by-step explanation:

 class frequency continuous class 0-5 13 0-5.5 6-11 10 5.5-11.5 12-17 15 11.5-17.5 18-23 8 17.5-23.5 24-29 11 23.5-29.5Median class is the class where the (2n+1)th term is lying.

In the given table, n=29

Therefore, (2n+1)th value is (230)th=15 which lies in the class interval 12.5−17.5

The upper limit of median class is 17.5
