Question

Find the mean of the set of data. round to the nearest 10th if necessary.

9.9, 10.8, 10.8, 6.2, 10.8, 7.2

Answer 1

The mean of the data set is 9.3 rounded to the nearest tenth

Explanation:

First you add them all together: 9.9 + 10.8 + 10.8 + 6.2 + 10.8 + 7.2 = 55.7

Then you divide it by how many numbers there are which is 6 in this situation:

55.7 ÷ 6 = 9.28333333333. but if we round it to the nearest tenth we get 9.3

So the answer is 9.3
