The cost of a daily newspaper varies from city to city. However, the variation among prices remains steady with a standard deviation of 6 g. A study was done to test the claim that the average cost of a daily newspaper is 35 g. Ten costs yield an average cost of 30 gwith a standard deviation of 4 g. Use hypothesis testing to determine if the data support the claim at the 5 % level?
