11.5

Answer 2

➪  We are going to form more thaulative frequency table:

Class−Interval c.f.(morethan)  More than 034  More than 531  More than 10 25  More than 1514  More than 206⇒  We are going to form less than cumulative frequency table:

Class−Interval c.f.(lessthan) Less than 5 3 Less than 10 9 Less than 15 20 Less than 20 28 Less than 25 34 ⇒  Median is where both less than and more then curves meet.

∴   Median=12.5
