The hourly wages of a sample of 130 system analysts are given below.

atroni [7]

Answer: b. 30%

Step-by-step explanation:

A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.

i.e. $CV=\dfrac{\sigma}{\mu}$

Given: mean = $\mu=90$

Variance = $\sigma^2 = 729$

$\sigma=\sqrt{729}=27$

Now, $CV=\dfrac{27}{90}=0.3$

in percent , $CV= 0.3\times100\%= 30\%$

Hence, correct option is b. 30%.
