Ответ:
So the equation for mean is (sum of all the numbers in the set)/(how many numbers there are). In this case, our numbers are {2,3,4,6,11,12,14,23} and there are 8 numbers total. Our equation will look like this:
Firstly, add everything on the numerator:
Next, divide, and your answer will be 9.37500, or approximately 9.38.
