A poll surveyed people in six countries to assess attitudes toward a variety of alternate forms of energy. Suppose 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. Response Country Great Britain France Italy Spain Germany United States Strongly favor 298 133 141 161 128 204 Favor more than oppose 309 222 348 368 272 326 Oppose more than favor 219 311 381 334 322 316 Strongly oppose 220 443 217 215 389 174 (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. State the null and alternative hypotheses. 1. H0: The attitude toward building new nuclear power plants is independent of the country. Ha: The attitude toward building new nuclear power plants is not independent of the country. 2. H0: The attitude toward building new nuclear power plants is not mutually exclusive of the country. Ha: The attitude toward building new nuclear power plants is mutually exclusive of the country. 3. H0: The attitude toward building new nuclear power plants is mutually exclusive of the country. Ha: The attitude toward building new nuclear power plants is not mutually exclusive of the country. 4. H0: The attitude toward building new nuclear power plants is not independent of the country. Ha: The attitude toward building new nuclear power plants is independent of the country. Find the value of the test statistic. (Round your answer to two decimal places.) ( ) Find the p-value. (Round your answer to four decimal places.) p-value = ( ) State your conclusion. 1. Do not reject H0. We cannot conclude that the attitude toward building new nuclear power plants is independent of the country. 2. Do not reject H0. We conclude that the attitude toward building new nuclear power plants is not independent of the country. 3. Reject H0. We conclude that the attitude toward building new nuclear power plants is not independent of the country. 4. Reject H0. We cannot conclude that the attitude toward building new nuclear power plants is independent of the country. (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? 1. Great Britain 2. France 3. Italy 4. Spain 5. Germany 6. United States Which country has the least favorable attitude? 1. Great Britain 2. France 3. Italy 4. Spain 5. Germany 6. United States
