Answer: 20
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, let's begin by adding the numbers.
15 + 28 + 25 + 22 + 11 + 12 + 27
This will be divided by how many numbers are in the set which is 7.
So we have [tex]\frac{15 + 28 + 25 + 22 + 11 + 12 + 27}{7}[/tex]
Adding the numbers, we get 140.
140 is divided by the number of numbers in the set or 7.
140 divided by 7 is 20.
So the mean of the set of data shown here is 20.
