Some integers are marked on a board. What is the range of these integers?
(a) 31
(b) 37
(c) 20
(d) 3

Solution:

Given, the data marked on a board is 0, 15, -11, -17, 6, 20, -4

We have to determine the range of these integers.

We know that the difference between the highest and lowest observations in a given data is called its Range.

Arranging the data in ascending order, we get

-17, -11, -4, 0, 6, 15, 20

The highest observation is 20

The lowest observation is -17

Range = highest observation - lowest observation

= 20 - (-17)

= 20 + 17

= 37

Therefore, the range is 37.
