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 72%, respectively. Random samples of size 150 are selected from each
of the three countries.
You want to test for evidence of a difference among the proportions across the three countries using
the 0.05 level of significance.
-Referring to Scenario 12-18, there is sufficient evidence to conclude that the
proportions between Canada and China are different at a 0.05 level of significance.
