Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants 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?

Use technology to calculate the P-value.
100- 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. 60+ 40- Country A 50% Country B 46% Country C 45% Country D 39% Identify the claim and state Ho and H₂. The claim is "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 power plants in their country." Let p, represent the population proportion for Country C and p2 represent the population proportion for Country D. State Ho and H₂ Choose the correct answer below. OA. Ho: P₁ P₂ OB.
