Question 1159005: Random samples of size 36 are taken from an infinite population whose mean is 80 and standard deviation is 18. What are the mean and standard error of the sampling distribution of sample means?
You can put this solution on YOUR website! The mean of the sampling distribution is the same as the population mean, which is 80
the standard deviation of the distribution of sample means of size 36 is the std dev of the population/sqrt(n)
and this is 18/sqrt(36)=3
sampling distribution is ~N(80, 3)
