Answer 1

Answer:

14.33333

Step-by-step explanation:

So we have the numbers:

15, 11, 11, 12, 13, 15, 13,  15, 15, 16, 16, 18, 12, 15, 18​

Next, add them all:

15 + 11 + 11 + 12 + 13 + 15 + 13 +  15 + 15 + 16 + 16 + 18 + 12 + 15 + 18​ = 215

Then, multiply it by how many numbers does that set have which is 15:

215 ÷ 15 = 14.33333

The mean is 14.33333 or simply 14
