Question 582136: A laptop manufacturer finds that the average time it takes an employee to load a laptop with software is 35 minutes with a standard deviation 15 minutes. Suppose you take a random sample of 64 employees. The standard deviation of the sample mean is: Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A laptop manufacturer finds that the average time it takes an employee to load a laptop with software is 35 minutes with a standard deviation 15 minutes. Suppose you take a random sample of 64 employees. The standard deviation of the sample mean is:
----
By the Central Limit Theorem the std of the sample means = 15/sqrt(64)
= 15/8
