The average price of homes sold in the U. D. in 2012 was $240,000. A sample of 144 homes sold in Chattanooga in 2012 showed an average price of $246, 000. It is known that the standard deviation of the population is $36000. We are interested in determining whether or not the average price of homes sold in Chattanooga is significantly more than the national average.
