Given a one independent variable linear equation that states

Given a one independent variable linear equation that states cost in $K, and given the following information, calculate the coefficient of variation and determine its meaning:

n = 12   (Y Y²) = 10591 = 314.475

Possible answers:
If we used this equation, we could typically expect to be off by ± 29.31%.
If we used this equation, we could typically expect to be off by ± 10.35%.
If we used this equation, we could typically expect to be off by ± 11.57%.
If we used this equation, we could typically expect to be off by ± 33.85%.
