To find the mean of the populations of the regions, you need to follow these steps:
- Add all the populations together.
- Divide the sum by the number of regions.
Here are the populations:
- Region 1: 20,200
- Region 2: 14,500
- Region 3: 18,800
- Region 4: 9,300
- Region 5: 2,200
Step 1: Calculate the total population.
\[ \text{Total} = 20,200 + 14,500 + 18,800 + 9,300 + 2,200 \]
Calculating that:
\[ 20,200 + 14,500 = 34,700 \] \[ 34,700 + 18,800 = 53,500 \] \[ 53,500 + 9,300 = 62,800 \] \[ 62,800 + 2,200 = 65,000 \]
So, the total population is 65,000.
Step 2: Divide the total by the number of regions.
There are 5 regions.
\[ \text{Mean} = \frac{\text{Total}}{\text{Number of Regions}} = \frac{65,000}{5} = 13,000 \]
Thus, the mean population is 13,000. The correct answer is:
13,000.
