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 1050 adults from Country A, 1056 adults from Country B, 1117 adults from Country C, and 1026 adults from Country D. At a = 0.07, can you reject the claim that the proportion of adults in Country A who favor building new nuclear power plants in their country is the same as the proportion of adults from Country B who favor building new nuclear 80- power plants in their country? Assume the random samples are independent. 100- 60- 40- 20- I Country A 49% Country B 47% O Country C 46% O Country D 35% Use technology to calculate the P-value. P-value = (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O Reject Ho because the P-value is less than the significance level a. O Fail to reject Ho because the P-value is greater than the significance level a. O Fail to reject Ho because the P-value is less than the significance level a. O Reject Ho because the P-value greater than the significance level a. Can you reject the original claim? Choose the correct answer below. Yes, at the 7% significance there is cient to reject O B. Yes, at the 7% significance level, there is sufficient evidence to reject the claim. OC. No, at the 7% significance level, there is insufficient evidence to reject the claim. OD N at the 70L eignificance lovel there ie eufficiont evidence to reject the claim

Question
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 1050 adults from Country A, 1056 adults from Country B, 1117 adults from Country C, and 1026 adults from Country D. At a = 0.07, can you reject the claim that the 100- 80- proportion of adults in Country A who favor building new nuclear power plants in their country is the same as the proportion of adults from Country B who favor building new nuclear 60- power plants in their country? Assume the random samples are independent. 40- 20- 0- Country A 49% I Country B 47% O Country C 46% O Country D 35% Identify the claim and state Ho and Ha. The claim is "the proportion of adults in Country A who favor building new nuclear power plants in their country is the proportion of adults from Country B who favor building new nuclear power plants in their country." Let p, represent the population proportion for Country A and p2 represent the population proportion for Country B. State Ho and Ha. Choose the correct answer below. О А. Но: Р1 > P2 Ha: P1 SP2 O C. Ho: P1 < P2 Ha: P1 2 P2 B. Ho: P1 + P2 Ha: P1 = P2 O D. Ho: P1 2 P2 Hạ: P1 <P2 O E. Ho: P1 = P2 Ha: P1 # P2 O F. Ho: P1 <P2 Hại P1 > P2 Find the standardized test statistic. Z= (Round to two decimal places as needed.) Use technology to calculate the P-value. P-value = (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below.
