I don't know what to do with this error:

get_average(alice) raised the following error: global name 'sudents' is not defined

```
lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}
# Add your function below!
def average(numbers):
sum(numbers)
total = sum(numbers)
return float(total) / len(numbers)
def get_average(student):
homework = average(sudents["homework"]) * 0.1
quizzes = average(sudents["quizzes"]) * 0.3
tests = average(sudents["tests"]) * 0.6
avg = homework + quizzes + tests
return avg
```

is the code I used; I tried adding a "students" list:

`students = [lloyd, alice, tyler]`

but that didn't help
