13.7142

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.

So we have 14 + 18 + 15 + 17 + 5 + 4 + 13 which is equal to 96.

86 will be divided by the number of numbers in the set which is 7.

So,  96 divided by 7 is equal to 13.7142.

So the mean of the data set is 13.7142.
