The operating costs for each machine for one day have an unknown distribution with mean 1610 and standard deviation 136 dollars. A sample, with size n=45, was randomly drawn from the population. Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution? Select the correct answer below: 3.02 20.27 25.34 30.41 34.47 136.00

20.27

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation

Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?

This is s when . So

So the correct answer is:

20.27

i dont know and i dont care for math bc it is a stupied subject
