In a moderately skewed distribution, if the mean is 45 and the mode is 39, the median is approximately:
Correct Answer: Option D
Explanation:
Using the empirical relationship: Mode ≈ 3×Median - 2×Mean. Rearranging: Median ≈ (Mode + 2×Mean)/3 = (39 + 90)/3 = 129/3 = 43. This approximation holds for moderately skewed unimodal distributions.
