Answer 1

Answer:

Given : The annual numbers of industrial accidents in a motor plant for the past 9 years are 300, 250, 110, 435, 693, 250, 375, 420 & 460.

To find : The range ?

Solution :

Arrange the data in ascending order,

110, 250,250,300,375,420,435,460,693.

Formula to find range is

Range = Maximum term - Minimum term

Maximum term = 693

Minimum term = 110

Substitute in formula,

Range = 693-110

Range = 583

Therefore, the range is 583.
