Answer 1

Formed the grouped frequency table , 108.2 gm is median Weight

Step-by-step explanation:

Class                      f              cf

60 - 80                  4              4

80 - 100                14              18

100 - 120               17              35

120 - 140                9              44

140 - 160                1               45

160 - 180                0              45

180 - 200              4                49

200 - 220              1               50

Median = 100 +  20 * ( 25 - 18)/17

= 100 + 8.2

= 108.2 gm is median Weight
