Final answer:
To find the population mean or sample mean, add all the values and divide by the total number of values.
Step-by-step explanation:
To find the population mean or sample mean, you need to calculate the average of the given values. For example, if the population is 2, 3, 11, 16, and 18, you can find the population mean by adding these values and dividing by the total number of values, which is 5 in this case.
Population Mean = (2 + 3 + 11 + 16 + 18) / 5 = 50 / 5 = 10
So, the population mean is 10.
