The only error that I can see with my code is that it doesn't output the correct answer as stated in the following message: get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

I instead expect it to return the correct answer as when I print get_average([alice]) I get the expected answer of 91.15.

```
lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],

}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
