100- 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 1129 adults from Country A, 1010 adults from Country B, 1040 adults from Country C, and 1055 adults from Country D. At a=0.09, can you reject the claim that the proportion of adults in Country C who favor building new nuclear power 80- plants in their country is greater than the proportion of adults from Country D who favor building new nuclear power plants in their country? Assume the random samples are independent. 60- Identify the claim and state Ho and Ha The claim is "the proportion of adults in Country C who favor building new nuclear power plants in their country is nuclear power plants in their country." Let p₁ represent the population proportion for Country C and p2 represent the population proportion for Country D. State Ho and Ha Choose the correct answer below. OA. Ho: P1 > P2 Ha: P₁ P2 OD.

100 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 1129 adults from Country A, 1010 adults from Country B, 1040 adults from Country C, and 1055 adults from Country D. At a = 0.09, can you reject the claim that the proportion of adults in Country C who favor building new nuclear power 80- plants in their country is greater than the proportion of adults from Country D who favor building new nuclear power plants in their country? Assume the random samples are independent. 60- 40- 20- 0- Use technology to calculate the P-value. P-value (Round to four decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O Fail to reject Ho because the P-value is less than the significance level x. O Reject Ho because the P-value is greater than the significance level a. O Fail to reject Ho because the P-value is greater than the significance level a. O Reject Ho because the P-value is less than the significance level α. Can you support the riginal claim? Choose the correct answer below. OA. Yes, at the 9% significance level, there is sufficient evidence to support the claim. OB. Yes, at the 9% significance level, there is insufficient evidence to reject the claim. Country A 50% Country B 49% Country C 45% Country D 40%
