Answer 2

Step-by-step explanation:

Here n=400. ∴

n

=200

Class Frequency Cumulative frequency(c.f.)

0-100 64 64

100-200 62 64+62=126

200-300 84 126+84=210

300-400 72 210+72=282

400-500 66 282+66=348

500-600 52 348+52=400

Cumulative frequency greater than 200 is 210, corresponds to the class 200−300.

Class 200−300 is the median class

l=200,
