For the study purpose, the mean of the observations is 148 gm and standard deviation is 17.4 gm. Approximately, the coefficient of variation equals to:
0.12
The Coefficient of Variation is the ratio of standard deviation to mean:
\[CV = \frac{\sigma}{\bar{x}} = \frac{17.4}{148} \approx 0.1176\]
Rounded to two decimals this is 0.12.
