Question

If the mean of 6 numbers increased by 3, by how much would the sum of

the 6 numbers have to increase? *
O 18
O 21
O 12
O 3
O 6

Answer 1

18

Explanation:

the mean is the average of the 6 numbers, in order for the total average to increase by 3 points, that is like saying each of the 6 values increased by 3 points each, 3 × 6 = 18, now each one would not actually have to increase by 3 each, as long as the total increase of adding all 6 numbers together was 18 points higher, then the average would be 3 points higher

Answer 2

I think 6x3=18
So, the answer is 18
