Given the following values 25, 7, 22, 33, 18, 15The population mean and population standard deviation are approximately:
Question
Solution 1
To calculate the population mean (average), you add up all the numbers and then divide by the number of values.
Step 1: Add up all the numbers: 25 + 7 + 22 + 33 + 18 + 15 = 120
Step 2: Divide by the number of values: 120 ÷ 6 = 20
So, the population mean is 20.
