Explanation:

- In statistics, a moderately asymmetrical distribution often follows the empirical rule or Pearson's rule.

- Pearson's rule suggests a relation as: Mean - Mode ˜ 3(Mean - Median)

- Given: Mode = 7.52, Median = 9.06

- Solving using the relation:

Mean - 7.52 ˜ 3(Mean - 9.06)

Solve for Mean:

Mean - 7.52 ˜ 3Mean - 27.18

2Mean ˜ 34.7

Mean ˜ 17.35/2

Mean ˜ 8.67

- Option 2: 8.67 is the correct answer.
