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 favor or oppose the building of new nuclear power plants. Country Response United States Great France Italy Spain Germany Britain Strongly favor 298 161 141 128 133 204 Favor more than oppose 309 368 348 272 222 326 Oppose more than favor 219 334 381 322 311 316 Strongly oppose 220 215 217 389 443 174 (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. O H: The attitude toward building new nuclear power plants is independent of the country. H: The attitude toward building new nuclear power plants is not independent of the country. O H: The attitude toward building new nuclear power plants is not mutually exclusive of the country. : The attitude toward building new nuclear power plants is mutually exclusive of the country. H: O H: The attitude toward building new nuclear power plants is not independent of the country. H: The attitude toward building new nuclear power plants is independent of the country. O H: The attitude toward building new nuclear power plants is mutually exclusive of the country. : The attitude toward building new nuclear power plants is not mutually exclusive of the country. H: Find the value of the test statistic. (Round your answer to two decimal places.)
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
