Question 841486
Q:
An April 2004 article on HearTheIssues.com stated that Americans have an average of 2.13 televisions per household. If the standard deviation for the number of televisions in a U.S. household is 1.6 and a random sample of 71 American households is selected, the mean of this sample belongs to a sampling distribution.
What is the standard deviation of this sampling distribution? (Give your answer correct to three decimal places.) 
-----------------------------------------------
A:
The standard deviation of the sample mean is equal to {{{sigma/sqrt(n)}}} where {{{sigma}}} is the population standard deviation and n is the sample size.
{{{sigma/sqrt(n)}}} = {{{1.6/sqrt(71)}}} = {{{highlight(0.190)}}}
