Answer: 90
Step-by-step explanation: The mean of a data set is equal to the
sum of the set of numbers divided by how many numbers are in the set.
So to find the mean of the data set
shown here, begin by adding the numbers.
Adding the numbers, we get 720.
This will be divided by the number of numbers in the set, or 8.
So we have 720/8 or 90.
So the mean of the data set shown here is 90.
