SE of x̄ Work with Steps for n = 15 & σ = 2.20
The below is the work with step by step calculation shows how to estimate the standard deviation of sampling distribution of mean for sample size n = 15 and population standard deviation σ = 2.20 to help grade school students to solve the similar SE of x̄ worksheet problems efficiently.
Workout :
step 1 Address the formula, input parameters and values
Input parameters
Population standard deviation σ= 2.20
Sampe size n= 15
Formula
SEx̄ = σ√n
step 2 Apply the values in SE of mean formula
= 2.20√15
= 2.20/3.873
SEx̄ = 0.568
0.568 is the standard error of sample mean.
