Solution

Let us arrange the weights in descending order:
3.1, 3.0, 2.9, 2.9, 2.8, 2.8, 2.7, 2.7, 2.6, 2.5, 2.5, 2.4, 2.3, 2.2, 2.1
(i) Highest weight: 3.1 Kg.
(ii) Lowest weight: 2.1 Kg.
(iii) Range = Maximum observation – Minimum observation
= (3.1-2.1) kg
= 1.0 Kg.
(iv) 4 babies weigh below 2.5 kg.
