Answer:
coefficient of variation = 12

Explanation:
Coefficient of variation can be calculated using the following rule:
coefficient of variation = (standard deviation / mean) * 100
We are given that:
standard deviation = 3
mean = 25

Substitute in the above equation to get the coefficient of variation as follows:
coefficient of variation = (3/25) * 100 = 12

Hope this helps :)
