Question

What is the coefficient of range for the following wages of 8 workers 80,65,90,60,75,70,72,85

Answer 1

$\textbf{Given:}$

$\textsf{Wages of 8 workers are}$

$\mathsf{80,65,90,60,75,70,72,85}$

$\textbf{To find:}$

$\textsf{Coefficient of range of the given data}$

$\textbf{Solution:}$

$\underline{\mathsf{Range:}}$

$\mathsf{=Greatest\;value-Smallest\;value}$

$\mathsf{=90-60}$

$\implies\boxed{\mathsf{Range=30}}$

$\mathsf{Now,}$

$\mathsf{Coefficient\;of\;range}$

$\mathsf{=\dfrac{Greatest\;value-Smallest\;value}{Greatest\;value+Smallest\;value}}$

$\mathsf{=\dfrac{90-60}{90+60}}$

$\mathsf{=\dfrac{30}{150}}$

$\mathsf{=\dfrac{1}{5}}$

$\mathsf{=0.2}$

$\textbf{Answer:}$

$\mathsf{Range=30}$

$\mathsf{coefficient\;of\;range=0.2}$

Answer 2

Step-by-step explanation:

Range= Greatest Value -smallest value

= 13-5

= 8

Range 8

Greatestvalue-Smallest value

cofficient of range Greatest + Smallest value
