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.

[Image Description: n =12, Summation of (Y-Yhat)² = 15000, Ybar=314.375]

1)   If we used this equation, we could typically expect to be off by ± $11.75K.

2) If we used this equation, we could typically expect to be off by ± $12.32K.

3) If we used this equation, we could typically expect to be off by ± 11.75%.

4) If we used this equation, we could typically expect to be off by ± 12.32%.
