Tourism patterns are difficult to forecast; they normally vary from country to country and sometimes even between places quite close to each other. In Hong Kong, a survey asked 1,600 people their favorite Asian destination for a short holiday. The results were as follows: 43% go to China, 23% go to Thailand, 20% go to the Philippines, 5% go to Cambodia, and the rest choose other countries. The same survey has been carried out in Macau, China only 1 hour from Hong Kong by jet boat, and the results were as follows: 48%, China; 20%, Thailand; 22%, the Philippines; 3%, Cambodia; and the remaining, other destinations. Would you conclude that the patterns are the same in the two cities?
