The coefficient of variation of a series...

The coefficient of variation of a series is 58. The standard deviation is 21.2. What is the arithmetic mean?

Text Solution

Verified by Experts

Given: CV=58,`sigma`=21.2
`CV=(sigma)/(X)xx100`
`implies " " barX=(21.2)/(58)xx100`
Substituting the values, we get
`barX=(21.2)/(58)xx100=36.6`
Arithmetic Mean=36.6
