Show answer & explanation
Correct answer: C
Answer: Import the statistics module and call statistics.mean on the list.
Example:
import statistics print(statistics.mean([1, 2, 3])) # Output: 2
Key points:
The statistics module provides a mean function that returns the arithmetic mean of numeric data.
The math and random modules do not have a mean function for lists.
If you do not want to import statistics, you can compute the mean manually with sum(data)/len(data), or use numpy.mean for arrays if numpy is available.
