**Question 14 (1 point)**

Once a week, Bill rows his boat from the island where he lives to the mainland. The journey time, \( X \) minutes, is normally distributed with mean \( \mu \) and standard deviation \( \sigma \). Given that \( P(X < 20) = 0.63 \) and \( P(X < 30) = 0.95 \), find mean \( \mu \). Write your answer in 3 decimal places.

[Answer box]

---

**Explanation:**

This problem involves understanding the properties of a normally distributed random variable. Here, the journey time \( X \) is normally distributed with an unknown mean \( \mu \). You are given probabilities associated with different journey times, which will help you find \( \mu \).
