Question
A population consist of multiple of five numbers where is 5, 10, 15, 20, 25, and 30 with sample size of 2. Find the population mean.
Solution
To find the population mean, you need to add up all the numbers in the population and then divide by the number of items in the population.
Here are the steps:
- Add up all the numbers: 5 + 10 + 15 + 20 + 25 + 30 = 105
- Count the number of items in the population: There are 6 items.
- Divide the sum by the count: 105 / 6 = 17.5
So, the population mean is 17.5.
