Answer: 12.73 is the mean.

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Add the numbers that are included: 191

How many dots?: 15

191 ÷ 15 = 12.73
