Answer 1

4.2

Explanation:

To calculate the average we must take all the values they give us and add them:

take 3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all up

3 + 4 + 5 + 3 + 4 + 5 + 6 + 5 + 4 + 3 + 2 + 3 + 4 + 5 + 6 + 4 + 8 + 4 + 3 + 2 = 83

We divide this result by the total number of values, which is 20, like this:

83/20 = 4.15

To round off, get closer to the nearest tenth number, of 15, it would be 20, therefore

the mean would be 4.2
