Answer:
The coefficient of variation after the tax is imposed is 0.033
Step-by-step explanation:
Given
--- mean
--- variance
Required
The coefficient of variation
The coefficient of variation is calculated using:
After the tax, the new mean is:
And the new variance is:
So, we have:
-22+(x/35)=-25
add 22 to both sides
x/35=-3
multiply both sides by 35 to cleaf raction
x=-105
number was -105
