A population has a mean mu= 72 and a standard deviation sigma= 6. Find the mean and standard deviation of a sampling distribution of sample means with sample size n= 36.
Homework Answers
Solution :
Given that ,
mean = 
= 72
standard deviation = 
= 6
n = 36
sampling distribution of sample means 
=
= 72
standard error
= /
n = 6 /
36=1
