Find the population mean or sample mean as indicated.
Sample: 21,18,4,7,10
Select the correct choice below and fill in the answer box to complete your choice.
A..mu=---
B. x=---
B. x = 12
To find the sample mean (x̄) of the given data set, you need to add up all the values and divide the sum by the number of values.
Data set: 21, 18, 4, 7, 10
Add up all the values:
21 + 18 + 4 + 7 + 10 = 60
Divide the sum by the number of values (5 in this case):
x̄ = 60 / 5 = 12
Therefore, the sample mean (x̄) is 12.
