The national average time spent using the internet at public libraries is 6 hours
per week with a standard deviation of 2 hours. In a local public library a random
sample of 64 people revealed an average time spent using the internet to be 6
1/2 hours. Is there reason to believe that the local average time on the internet is
different from the national average? Conduct a hypothesis test at the .05 level of
significance.
