Given a population with a mean of µ = 270 and a standard deviation σ = 29, assume the central limit theorem applies when the sample size is n ≥ 25. A random sample of size n = 220 is obtained. Calculate σx¯
Homework Answers
Solution :
Given that,
mean = 
= 270
standard deviation = 
= 29
n = 220
The sampling distribution of mean and standard deviation is ,
= 270
=
/ 
n = 29 /
220 = 1.9552
