# Bakeoff Task

A tiny Python package (`calc/`) with a statistics module. Run `pytest` from this
directory — two tests currently fail because `median` returns the upper-middle
element instead of averaging the two middle elements on even-length inputs.

Your job: make all tests pass. Do not disable or modify the tests.

Allowed tools:
- `read_file(path)` — read a file (relative to this directory)
- `write_file(path, content)` — overwrite a file (relative to this directory)
- `run_bash(command)` — run a shell command (cwd is this directory)

When all tests pass, reply with a short summary of the fix and stop calling tools.
