How do U.S. residents who travel overseas for leisure differ from those who travel for business? The following table shows the breakdown by occupation. Leisure Business Occupation Explain why we can, or cannot, use a chi-square test to travelers (%) travelers (%) learn whether these two distributions differ significantly. Professional/technical 36 39 O We cannot use a chi-square test with these data Manager/executive 23 48 because we do not have the actual counts of the Retired 14 3 travelers in each category. We also do not know if the sample was taken randomly or if the samples are independent. O We can use a chi-square test with these data because Student 7 Other 20 7 Total 100 100 we do have the actual proportion of the travelers in each category.
