From 1986-1996, drug overdose deaths per 100,000 began to rise. numbers for each year are 2,1,2,2,1,2,2,3,3,3,3. what is the mean of these statistics?

To find the mean, add all the numbers together and then divide it by how many numbers there are:
2+1+2+2+1+2+2+3+3+3+3=24
There are eleven numbers total, so divide 24 by 11.
24/11=2.1818181818181818
The mean of the statistics is approximately 2.2

The correct answer is -4
