Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants in their country. The survey included random samples of 1128 adults from Country A, 1026 adults from Country B, 1008 adults from Country C, and 1061 adults from Country D. At a = 0.01, can you reject the ciaim that the 100- proportion of adults in Country C who favor building new nuclear power plants in their country is greater than the proportion of adults from Country D who favor building new nudear 80 60 40- 20 power plants in their country? Assume the random samples are independent. I Country A 50% I Country B 46% O Country C 45% O Country D 39% Choose the correct answer below.
