Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants 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 claim that the
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 nuclear 80-
power plants in their country? Assume the random samples are independent.
