Follow-up Question
**Educational Content: Understanding Bone Growth in Males**

Determining age can be challenging when there are no official birth records. Bone growth ends when growth plates at the ends of long bones fuse. Once this occurs, growth ceases, and the individual is biologically considered an adult. 

The fusion age for male growth plates follows a normal distribution, with a mean of 18.7 years and a standard deviation of 16.1 months. Below are some statistical analyses related to this biological process:

**a) Probability of Fusion After Age 21:**
The probability that a male's growth plates fuse after age 21 is **0.0436**.

**b) Probability of Fusion Before Age 16:**
The probability that a male's growth plates fuse before age 16 is **0.0222**.

**c) Proportion Fusing Between Ages 15 and 16:**
The proportion of male growth plates that fuse between ages 15 and 16 is **0.0192**.

**d) Unusual Fusion Age of 23 or Older:**
In this part, users are prompted to assess whether it would be unusual for male growth plates to fuse at age 23 or older. 
Users can interact with dropdown menus to choose if the event is unusual based on calculated probabilities and distribution.

This exercise helps understand the typical age range for growth plate fusion in males and the variability around this biological milestone.
