Question

variance is 148.6 and Mean is 40 then the coefficient of variation is​

Answer 1

Answer

If mean of the given dist. be xˉ and S.D be σthen given xˉ =40,σ 2 =1486∴ Coefficient of variation = xˉ σ = 401486 =.9637

Answer 2

Answer:

C)30.48

Step-by-step explanation:

variance of x=148.6

SD=√148.6=12.19

CV=SD/X×100

=12.19/40×100

=30.475
