Despite Zimbabwe’s shattered economy, with endemic poverty and widespread political strife and repression, thousands of people from overseas still head there every year (BBC News, August 27, 2008). Main attractions include the magnificent Victoria Falls, the ruins of Great Zimbabwe, and herds of roaming wildlife. A tourism director claims that Zimbabwe visitors are equally represented by Europe, North America, and the rest of the world. Records show that of the 380 tourists who recently visited Zimbabwe, 148 were from Europe, 106 were from North America, and 126 were from the rest of the world.

a. A recent visitor to Zimbabwe believes that the tourism director’s claim is wrong. Set up the competing hypotheses to test the visitor’s belief.

b. Conduct the test at the 5% significance level. Do the sample data support the visitor’s belief?
