Number of workers (Frequency) f

1

Cumulative frequency less than type

100-120

12

Less than 120

12=12

120-140

14

Less than 140

(12+14)=26

140-160

8

Less than 160

(26+8)=34

160-180

6

Less than 180

(34+6)=40

180-200

10

Less than 200

(40+10)=50

Total

n=50

n=50 gives n/2=25

On the graph, we will plot the points (120, 12), (140, 26), (160, 34), (180, 40), (200, 50).
