**Question:**

Given that `my_val` is a list of float values, which of the following is an example of a built-in function?

1. ( ) `my_val.capitalize()`
2. ( ) `my_val.title()`
3. ( ) `len(my_val)`
4. ( ) `average(my_val)`

**Explanation:**

This question is about identifying a built-in function that can interact with a list of float values. Built-in functions are pre-defined in Python and can operate on different data types. In this context:

- `my_val.capitalize()` and `my_val.title()` are methods associated with string objects, not lists. Therefore, they are not applicable for a list of floats.
- `average(my_val)` is not a standard built-in function in Python. Calculating the average would typically involve using a library like NumPy or manually calculating it.
- `len(my_val)` is a built-in function in Python that returns the number of items in a list, making it the correct answer.
