Question

The weight of new born babies (in kg) in a hospital on a particular day are as follows:
$2.3,2.2,2.1,2.7,2.6,3.0,2.5,2.9,2.8,3.1,2.5,2.8,2.7,2.9,2.4$
Determine the range.

Answer 1

Given that the weight of new born babies (in kg) in a hospital on a particular day are as follows:

$2.3,2.2,2.1,2.7,2.6,3.0,2.5,2.9,2.8,3.1,2.5,2.8,2.7,2.9,2.4$

first of all arrange data in ascending order

$2.1,2.2,2.3,2.4,2.5,2.5,2.6,2.7,2.7,2.8,2.82.9,2.9,3.0,3.1$

Here observe that

highest weight of new born baby is $3.1kg$.

lowest weight of new born body is $2.1kg$

we know

Range = Highest - lowest

$=3.1kg-2.1kg$

Range $=1.0kg$
