13.3

Step-by-step explanation:

There is an equation that helps

mean= (All of the numbers in the data added) divided by (the number of numbers in the data)

What that mean is:

1.) Add 20, 5, 7, 17, 16, and 15

2.) divided by 6 (because there is 6 numbers in the data)

3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)

which in this case it should be 13.33333...=13.3
