Explanation:
To find the value of skewness, we can compute it using the sample standard deviation and the third moment:
. Calculate the sample standard deviation ($s$): $s = \sqrt{3,893.2658} \approx 62.396Skewness = \frac{\frac{1}{n} \sum_{i=1}^{n} (x_i - \hat{\mu})^3}{s^3}Skewness = \frac{-13,476.784 / 200}{(62.396)^3} = \frac{-67.38392}{242,927.98} \approx -0.00027738$Rounding to 7 decimal places, the skewness is approximately -0.0002774. Therefore, Option A is correct.
