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 randomsamples of 1051 adults from Country A, 1120 adults from Country B, 1048 adults from Country C, and 1013 adults from Country D. At a = 0.05, can you support the claim that theproportion of adults in Country B who favor building new nuclear power plants in their country is different from the proportion of adults from Country C who favor building newnuclear power plants in their country?
