The amount that households pay service providers for access to the Internet varies quite a bit, but the mean monthly fee is $48 and the standard deviation is $20. The distribution is not normal: Many households pay a base rate for low-speed access, but some pay much more for faster connections. A sample survey asks an SRS of 500 households with Internet acess how much they pay per month. Let x be the mean amount paid by the members of the sample. 8 Calculate the mean and the standard deviation of the sampling 1 distribution of x. Interpret the standard deviation.
