Step-by-step explanation:
Age Frequency Cumulativefrequency
14.5−19.5 53 53
19.5−24.5 140 193
24.5−29.5 98 291
29.5−34.5 32 323
34.5−39.5 12 335
39.5−44.5 9 344
44.5−49.5 5 349
49.5−54.5 3 352
54.5−59.5 3 355
59.5andabove 2 357
N=357
⇒ N=357 then,

The cumulative frequency just greater than
2
N
is 193, then the median class is 20−24 such that
l=19.5,f=140,F=53,h=24.5−19.5=5.
⇒ Median=l+
