 A random sample of 81 tourists in Chattanooga showed that they spent an average of $2000(in a week) with a standard deviation of $100 and a sample of 64 tourists in Ontario showed that they spent an average of $2500(in a week) with a standard deviation of $144. We are interested in determining if there is any significant difference between the average expenditures of those who visited the two cities? Test the hypothesis at alpha=0.05 and write all the steps.
