Answer:
6.75
Step-by-step explanation:
class frequency(fi) cumulative frequency (cf)
3-4 1 1
4-5 2 3
5-6 1 4
6-7 1 5
7-8 3 8
8-9 0 8
9-10 0 8
10-11 0 8
11-12 0 8
12-13 1 9
N=9
N÷2=9÷2=4.5
7-8 is median class
thus L=7
cf=5
f=3
h=1
median = L+[(n÷2-cf)÷2]×h
=7+[(4.5-5)÷2]×1
=7+(-0.5)÷2
=7+(-0.25)
=7-0.25
=6.75
