Answer 2

Given,

The sum of the highest and the lowest value = 80

The coefficient of range = 0.625

To Find,

The highest and lowest term difference.

Solution,

The coefficient of the range is calculated by using the below formula:

$coefficient of range = \frac{ Difference of the highest and lowest value}{Sum of the highest and lowest value}$

On substitution of the given values in the formula,

That is,  coefficient of range = 0.625

The sum of the highest and lowest values = 80

⇒$0.625 = \frac{Difference of the highest and lowest value}{80}$

On cross multiplication,

⇒$Difference between highest and lowest value =( 0.625)(80)$

⇒$Difference between highest and lowest value = 50$

Henceforth, the difference between the highest and lowest values is 50.
