Question

1. Find the coefficient of variation of 24, 26, 33, 37,29,31.​

Answer 1

Answer:

2,7,4,12,2 are the coffecients

Answer 2

Answer:

24, 26, 33, 37,29,31.

Mean = \frac{\text{Sum of observations}}{\text{No. of observations}}

Mean = \frac{24+26+33+37+29+31}{6}

Mean = 30

Standard deviation : \sqrt{\frac{\sum(x_i-\mu)^2}{n}}

Standard deviation : \sqrt{\frac{(24-30)^2+(26-30)^2+(33-30)^2+(37-30)^2<strong>+</strong>(29-30)^2+(31-30)^2}{6}}

Standard deviation : 4.32

Formula of coefficient of variation : CV =\frac{\sigma}{\mu} \times 100

CV =\frac{4.32}{30} \times 100

CV =14.4

Hence the coefficient of variation of 24, 26, 33, 37,29,31. is 14.4
