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 |
- a. How large was the sample in this poll?
- 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?
- 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?
