Question

recall that if $mu$ represents the population mean and $sigma$ represents the population standard deviation, then the population coefficient of variation (cv) is defined to be $cv=\frac{sigma}{mu}cdot100%$. compute the coefficient of variation (in percent) when $mu = 350$ and $sigma = 7$. $cv=\frac{sigma}{mu}cdot100%=\frac{7}{square}cdot100%=squarecdot100%=square%$

Explanation:

Step1: Substitute values into formula

$CV=\frac{\sigma}{\mu}\times100\%=\frac{7}{350}\times100\%$

Step2: Simplify the fraction

$\frac{7}{350}=\frac{1}{50}$
So $CV = \frac{1}{50}\times100\%$

Step3: Calculate the percentage

$\frac{1}{50}\times100\% = 2\%$

Answer:

$2\%$
