Question

if means is 20,SD10 then coefficient of variation is​

Answer 1

Answer:

Given σ=20, coefficient of variation =50 %

We know coefficient of variation =

x

ˉ

σ

×100=50

⇒

x

ˉ

=2×σ=40

Answer 2

Answer:

Given σ=20, coefficient of variation =50 %

We know coefficient of variation =xˉσ×100=50

⇒xˉ=2×σ=40
