Answer: The answer is 1.67
Step-by-step explanation:
First, find the mean by adding all of the numbers and divide them by how many numbers there are, so 17+15+16+20+15+19=102 Then 102/6= 17. Then take the mean and subtract it by every number, and make sure it is the number’s absolute value.
17-17=0, 15-17=2, 16-17=1, 20-17=3, 15-17=2, 19-17=2. Then add all of those numbers and divide them by how many numbers there are. 0+2+1+3+2+2=10. 10/6=1.67
