Short Answer

SCENARIO 7-8
A consulting firm that surveyed consumers' holiday shopping behavior found that the percentage of
consumers from the U.S., Canada, and China who said that they planned to spend more on holiday
shopping were 40%, 34% and 73%, respectively. Treat these results as representations of the
populations. Random samples of size 150 are selected from each of the three countries.
