Answer: 5.81818181818
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 [tex]\frac{3 +3+4+5+6+6+7+7+7+8+8}{11}[/tex] and notice that I put an 11 on the bottom since there are 11 numbers.
Adding the numbers, we get 64. This will be divide by how many numbers are in the set or 11.
[tex]\frac{64}{11} = 5.81818181818[/tex]
Therefore, the mean of the data set is 5.81818181818.
