Answer: Negatively skewed.

- C Negatively skewed
- D Normal
Correct answer: C. Negatively skewed
Explanation: Negatively skewed (left skewed): long tail to the left, mode > median > mean.
In a perfectly normal (bell-shaped) distribution, mean, median, and mode all coincide at the centre; about 68% of data falls within 1 standard deviation of the mean, 95% within 2, and 99.7% within 3 - the empirical rule used to judge how typical or extreme a value is.
