What is the mean of the set of numbers?
{–8, –4, –3, –11}
Question 3 options:
–4.5
4.5
–6.5
6.5
The mean of a set of numbers is calculated by adding up all the numbers in the set and then dividing by how many numbers there are in the set.
In this case, the sum of the numbers is -8 + -4 + -3 + -11 = -26. There are 4 numbers in the set, so the mean is -26/4 = -6.5.
Therefore, the best answer is -6.5.
