Question

According to the line graph, from 2003-2007, the number of drug-induced deaths continued to rise at a faster rate than all others. The numbers for each year are, roughly, 30,000, 30,000, 35,000, 40,000, 40,000.

What is the mean of these statistics?

175,000
40,000
35,000
30,000

Answer 1

`\bar{x}=35,000` drug induced deaths

Explanation:

The mean is one of the central measures, (as well as median, mode). It is given by this:

`\bar{x}=(30,000+30,000+35,000+40,000+40,000)/(5)=(175,000)/(5)=35,000`

So 35,000 deaths is one of the central measure of this statistics. It gives us a central value of how many drug induced deaths, was central to these if we could plot a normal dstribution, with these data.

Answer 2

35000

Explanation:

1) Add up 30000+30000+35000+40000+40000

2) Divide that total by 5 (the number of items you added together in the first step)

3) You get 35000
