find the mean 0, 0,0, 1, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 9

Answer 1

The mean is calculated by adding up all the numbers and then dividing by the total count of numbers.

0 + 0 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 3 + 3 + 3 + 3 + 3 + 3 + 4 + 4 + 9 = 45

There are 18 numbers in the list.

Mean = 45 / 18 = 2.5

Therefore, the mean of the numbers in the list is 2.5.
