15 0 1 4 5 5 7
16 2 5 5 6 8 9

20 3 5 5
21 1 2 6 6 6 8
131 is the weight of the lightest person in the group.
If we look closely the stem has the 13 as the lowest number. And corresponding to it the least number is 1.
Therefore the lightest weight person is 131 .All other weights are greater than 131 e.g 132 , 134 and 136 .
The data shows there are 131 ,131, 132,132,134,134, and 136 weights in the least weight group. So out of these 131 is the smallest.
