Chapter 12.2, Problem 16E

As the price of oil rises, there is increased worldwide interest in alternate sources of energy. A Financial Times/Harris Poll surveyed people in six countries to assess attitudes toward a variety of alternate forms of energy (Harris Interactive website, February 27, 2008). The data in the following table are a portion of the poll’s findings concerning whether people favor or oppose the building of new nuclear power plants.

	Country
Response	Great Britain	France	Italy	Spain	Germany	United States
Strongly favor	141	161	298	133	128	204
Favor more than oppose	348	366	309	222	272	326
Oppose more than favor	381	334	219	311	322	316
Strongly oppose	217	215	219	443	389	174

1. a. How large was the sample in this poll?
2. b. Conduct a hypothesis test to determine whether people’s attitude toward building new nuclear power plants is independent of country. What is your conclusion?
3. c. Using the percentage of respondents who “strongly favor” and “favor more than oppose,” which country has the most favorable attitude toward building new nuclear power plants? Which country has the least favorable attitude?
