Answer 1

Answer:

commulative frequency is given we have to find frequency:-

6

15-6=9

29-15=14

41-29=12

60-41=19

70-60=10

total:-70

70/2=35

Step-by-step explanation:

formula for finding median:-

L+(n/2-cf)/f×h

30+(70/2-29)/12×10

30+(35-29)/12×10

30+(6/12)×10

30+60/12

360+60/12

420/12

=35 Answer
