Answer: 8.3
Explanation:
The mean is the average of a data set; it is the number that falls directly in the middle of the data set.
The formula to find the average is: a=sum of terms/ number of terms.
Therefore, we just add up all the values in the data set and divide by how many numbers there are.
3+9+10+10+4+10+10+10/8 = 8.25. We added up all the numbers and then divided by how many numbers there were, which was 8.
8.25 rounded to the nearest tenth is 8.3.
Your answer is 8.3
