error message:

get_average(alice) returned 93.4 instead of the expected 91.15

the code:

```
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 = {

"tests": [100.0, 100.0]
}
# Add your function below!
def average(numbers):
total = float(sum(numbers))/len(numbers)
return total
def get_average(student):
homework = average(student['homework']) * 0.6
quizzes = average(student['quizzes']) * 0.3
tests = average(student['tests']) * 0.1
sum = homework + quizzes + tests
return sum
```
