In this task you will be given a list of numbers and you need to find the mean (average) of that list. The mean of a list can be found by summing every number in the list then dividing the result by the size of that list. The output should be rounded to 3 decimal places.
One example is below.
Q: [1,3,5]
A: 3.000
Rationale: The mean of the input list is (1+3+5)/3, which equals 3. This is a good example.
Q: [64.738, 65.665, 96.525, -45.422, -87.911]
A:
18.719
