Question 880706
The mean of salaries for a total of 350 staff is: µ = $50,500
 The standard deviation for the 350 staff members is: σ = $18,800
 (These numbers have been rounded to the nearest $100.00) 
So the question is: If all possible samples of size 40 were taken from this population, what would you expect the mean and standard deviation of these samples means to be?? 
-------
Using the Central Limit Theorem::
mean of the sample means = the mean of the population = 50,500
std of the sample means = 18,800/sqrt(40)
