Question

A population has a mean mu equals=75 and a standard deviation sigmaσequals=8. Find the mean and standard deviation of a sampling distribution ​( muμx​ &​) of sample means with sample size n=64

Answer 1

Solution :

Given that,

mean = = 75

standard deviation = = 8

n = 64

The sampling distribution of mean and standard deviation is ,

= 75

= / n = 8 / 64 = 1
