Task Prompt
I'm reviewing the barber shop data in my PC files and'd like to know what percentage of clients were female and the average age of those female clients. Round both the percentage and average age to two decimal places

# Virtual Filesystem
You work in a terminal over a virtual filesystem. Read files with shell
commands.
Command output comes back whole, however long. Some files here are large,
so point `grep -r`, `rg`, `find` and `cat` at the directory or file you
need rather than at a whole mount.
| path | what it is |
|---|---|
| `/data` | Your files. |
| `/tmp` | Scratch space, in memory. || name | workspace-filesystem |

# Available commands
Standard Unix commands, among them:
cat head tail ls find grep wc sort uniq cut tr sed awk
diff tee xargs jq
with pipes, `>` redirection and `$(...)` substitution.
Do not probe the machine with `which`, `type`, `--version`, `env`, `ps`,
`echo $PATH`, `ls /usr/bin` or `cat /usr/bin/<command>`: they tell you
nothing about the task.
A filename with a space in it needs quoting, as it would in any shell.
## airtable
Use `airtable <command> '<JSON arguments>'`. Run `airtable <command> --help`
to get more information.
```sh
airtable list-bases '{}'
```
| Command | Arguments | Description |
|---|---|---|
| `airtable list-bases` | `{}` | List all accessible Airtable bases |
## arxiv
Use `arxiv <command> '<JSON arguments>'`. Run `arxiv <command> --help` to
get more information.
```sh
arxiv search-papers '{"query":"QUERY","max_results":5}'
```
| Command | Arguments | Description |
|---|---|---|
| `arxiv search-papers` | `{query: str, max_results?: int, date_from?: str, date_to?: str, categories?: list[str]}` | Search for papers on arXiv with advanced filtering |
## python3
Execute Python code and return stdout and stderr. Code can be pasted into a
`.py` file and run with `python3`. Python cannot launch subprocesses or make
direct network requests. Run the documented service commands directly in
the shell. Use Python for local file processing and generating JSON
arguments.| name | workspace-commands |
