To find the mean of the populations in the different regions, you need to follow these steps:
- Add all the populations together.
- Divide the total 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. \[ 20,200 + 14,500 + 18,800 + 9,300 + 2,200 = 64,000 \]
Step 2: Divide the total by the number of regions (which is 5). \[ \text{Mean} = \frac{64,000}{5} = 12,800 \]
Since 12,800 is not one of the options provided, let's check if we have made any errors in the calculations or if we can find the best-fitting option.
Checking the total again:
- 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 correct total is actually 65,000.
Now, divide by the number of regions: \[ \text{Mean} = \frac{65,000}{5} = 13,000 \]
Thus, the mean population of the regions is 13,000.
