Answer 1

Given:

The data values are 21, 18, 37, 42, 47, 75, 66.

To find:

The range of the given data set.

Solution:

The data values are

21, 18, 37, 42, 47, 75, 66

Arrange these values in ascending order.

18, 21, 37, 42, 47, 66, 75

Now,

           = 75 - 18

           = 57

Therefore, the range of given data set is 57.
