Answer:

Median is 35

Step-by-step explanation:

Class Interval Frequency Cumulative Frequency

10-20 4 4

20-30 24 28

30-40 4 32

40-50 8 40

50-60 6 46

60-70 8 54

70-80 6 60

n/2 = 60/2 = 30

Median class is 30-40

Median = l +[ ( n/2 - cf) / f ] x h

= 30 + [ (30 - 28) / 4 ] x 10

= 30 + [ ( 2 ) / 4 ] x 10

= 30 + [1/2] x 10

= 30 + 5

Median = 35
