Question

The weights 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

In descending order first we write larger number and lowest last.

$3.1,3.0,2.9,2.9,2.8,2.8,2.7,2.7,2.6,2.5,2.5,2.4,2.3,2.2,\mathrm{2.1.}$

Range = maximum - minimum

$=3.1-2.1$

$=1$ kg.
